Computers as Components, Second Edition: Principles of Embedded Computing System Design

The vast majority of existing computers are embedded in the myriad of intelligent devices and applications-not in desktop machines. We are witnessing the emergence of a new discipline with its own principles, constraints, and design processes. Computers as Components is the first book to teach this new discipline. It unravels the complexity of these systems and the tools and methods necessary for designing them. Researchers, students, and savvy professionals, schooled in hardware or software, will value the integrated engineering design approach to this fast emerging field. * Demonstrates concepts and techniques using two powerful real-world processors as case studies throughout the book: the ARM processor and the SHARC DSP (digital signal processor). * Illustrates the major concepts of each chapter with real-world design examples such as software modems, telephone answering machines, and video accelerators. * Teaches the basics of UML (Unified Modeling Language) and applies it throughout the text to help you visualize stages in the design process. * Illustrates real-time operating systems using the POSIX real-time extensions and Linux. * Describes performance analysis and optimization of embedded software, including the effects of caches.

Not Recommended
This book was the required text for a class or I would not have purchased it. It is poorly organized and poorly written. The author provides an annoying amount of superfluous commentary and makes unnecessary digressions, both of which obscure the points he must be trying to make, and the content is sometimes repetitious. Finally, the book contains grammatical errors and the text includes what must surely be editorial content such as "stet" and "the acronym is the name", rendering some sentences unintelligible. Most books have their faults, but this one has too many to make it a worthwhile purchase; there are better texts which cover the same material.

explains hierarchy of design, from devices to operating system
The average person in the US now uses a computer. Typically running a Microsoft operating system or unix or linux. Yet there is an entire ecosystem of embedded computers out there, invisible to most people. Wolf's text explains how you can program such computers as well as design the circuitry in which they might exist. Here, "computer" in the book essentially means microprocessor plus some off-chip memory. The book surveys two main microprocessor families - ARM and SHARC. These are not the most common microprocessors. (Which might be by Motorola.). But Wolf chooses them to illustrate different design ideals for their instruction sets.

One nice thing about the book is that you get a direct grasp of the hierarchy of design and logic. Climbing from the low level devices of latches, gates, flip-flops and the like, to the microprocessor and its machine language, to the corresponding and far easier to use assembly language. Then, upwards to an operating system.

Good intro to embedded development
Do you know what percentage of all computers run Windows or some kind of Unix? Guess. I'll give you the answer later.

This book is about all the other computers out there - the ones in your car's airbags and antilock brakes; in your watch, cellphone, TV and its remote, CD player, and computer keyboard; in your implanted defibrillator.

Wolf starts with an introduction in terms of a personal-scale, practical example. Next he goes into what a CPU is in lots more detail than most programmers ever think about - the kind of detail you need when the CPU interacts so intimately with the other components in the system. Maybe you never heard of the ARM or SHARC processors (unless you already do embedded work), but they're good representative choices. ARM is an incredibly common core architecture, with supervisor mode and memory mapping, what it takes to run a "real" OS, whether it does or not. SHARC is a signal processor - a real processor, but with extras for fast artihmetic processing. Together, the two stand adequately for a large fraction of the embedded processors in use.The next chapter goes over hardware basics: the bus, memory mapped IO, interface issues, and in-circuit debugging.

The rest of the book generally covers higher level issues: software design, embedded and real-time OSs, coprocessors, and networks. Although coverage of IIC and similar board-level communication is good, I found the ethernet discussion weak. Anyone working at this level is likely to need 802.2 protocols, which I did not see mentioned. The book's strengths far outnumber its occasional soft spots, though.

Embedded computing is a huge, many faceted field, so no book can cover more than a tiny fraction of what it means. Still, this addresses a broad, useful range what you need to program 99% of the computers out there - because only about 1% run Windows or Unix.

PlayStation 3 Component AV Cable
Excellent Customer Service and Fast Postage to Australia.
The PS3 Component cable works perfectly with my PS2 and made a big difference to the graphics on a HD TV. I am very happy with the product, the price and service.

Can't believe the improvement in graphics.
My HDTV didn't have HDMI but with this cable I don't need it. The improvement in graphics is incredible, My order was delivered as stated and in excellent shape. I am extremely happy with my order.

Great picture
Great quality, but HDMI offers a slightly better picture. I use this for my HD PVR.

It does make a difference.
I just bought a new flatscreen t.v. for my room and figured that I'd upgrade the video connection to the PS2 also. Well, I wasn't sure how much difference it would make, but this is a noticeable improvement over the standard composite cables. It made the picture sharper and cleaner. I highly recommend it if you've just upgraded your television (especially if it's a smaller room and you've got to sit closer to the screen). Now, games definitely still look fine via the composite cables, but if you've got a few extra dollars, I'd say it be worth it to upgrade.

Cable works great on my PS2
I was a little hesitant to get this cable for my PS2 because I have one of the older (fat) models and there were mixed reviews about whether it would work or not. I took a risk and got one and I'm very glad I did. It plugs in just fine in the back of my PS2 and I can see a big difference in quality. It's not HDMI quality mind you, but that's only because most games don't run that high of a resolution, but it does look a lot better then using the RCA cable connection.

A couple of things to keep in mind if you're getting this for a PS2.
1. Before attaching this cable to your PS2, start your PS2 without a disk and go to the video output option and change it from RGB to Y, CB/PB, CR/PR. Once you do that, then it should display fine.

2. Many people complain that this make it so you can't play PS One games on flat screen tv's. I think this has to do more with the TV itself rather than the cable. I have a Samsung 42" TV and it plays PS One games just fine. Because PS One games use a much lower resolution than PS2 games, your flat screen TV may not be about to display that low of a resolution. Luckily mine does, but if you play a lot of PS One games, you may want to keep the RCA connection nearby just in case.

Ok for the price
This is a decent shelf system. The price was good but it is a bit flimsy. It is also a bit too short for two shelves.

Awesome
This is an awesome shelf for your DVD player, Cable box, and whatever else you have. We are using it to keep things out of our toddlers reach. It's extremely sturdy and gives the entertainment wall some style.

Pyle Component speakers
I was looking for replacement speakers to go into the wooden cabinets of a pair of Baby Advent shelf speakers. I have had the Advents for 20 years and they were sounding tired. These speakers were cheaply priced and I figured I would give them a try. I am really glad I did. They sound excellent and can handle significant amounts of volume. Both the 6.5 inch speakers and the crossovers are well made. The large magnets, poly cones and rubber surounds make the 6.5's a pretty beefy pair of speakers for their size. If there is a deficiency in this kit it is the tweeters. they look cheaply made and sound just a little thin. Over all a lot of speaker for small a price.

Great Small sub kit for the money
I put these in the soundbar of a 2008 jeep wrangler and they sound great. They seem like good quality speakers. I would recommend this kit to anyone.

Pyle Component Kit
Got here quickly, kudos to Amazon and fed ex for the super fast delivery I ordered it last Friday evening and received it today, only 2 business days!! Amazon even sent my phone a text message once they confirmed that it had been delivered. These speakers are not the easiest thing to install so if you do not have any experience installing stereo equipment I would push you towards a standard set of 3 or 4 way speakers.. if you know what your doing these speakers are pretty straight forward if you have any knowledge of stereo systems or even common sense. the difficult part is getting it to look good and hide the crossovers (assuming you want to hide them)... now to the product itself.

When I opened the box it smelled of Chinese plastic.. these are made in china like everything else. but their build quality is fair/good speakers feel pretty rigid and I see no problems with them holding up for years under normal use.. but on those hot summer days I would be careful not to crank it up too much the plastic seems to be the type that could warp under high heat and movement... unfortunately there is no room in my garage so my install was stuck to the outdoors and being April in Oregon my install was cut to a halt after the first speaker due to me getting soaked in the rain (I have a small car.. not much room to install door speakers with the doors closed)

Anyway the side I did looks clean and professionally done and has the sound of a more expensive set these speakers perform at the same level of a 70-80$ pair of speakers from brands like sony, pioneer or kenwood.. keep in mind they are no infinity or kicker but do sound very good and are just about the best bang for the buck you can get!!!

Ohh and to the people complaining about the wire that comes with the speakers... the wire that comes with it is thicker than 90% of cars stock audio wiring.. so unless you plan on replacing ALL the audio wire putting larger gauge wire to the speakers is a complete and total waste not to mention these are only ~50 watt RMS speakers you don't need 8 gauge subwoofer wiring to make them work the smaller wire works just fine and they give you more than enough to suffice.

I'm very impressed with the improvement of the overall sound quality of my system with only one speaker.. the tweeters are loud and have a good range and can get very loud if you set them up for it and the woofers make a good deal of bass it wont replace a sub but for someone who listens to less bassy music it will do well.... I'm excited to install the other speaker and am anxiously awaiting my pyle audio 4 way speakers for the rear!!!! kudos pyle you guys have come a long way in the past years.

So far I'd recommend them to anyone.

*UPDATE*
Got them both installed and took out my old rotted out rear speakers and these things sound awesome... excellent bass.. far more than expected. At half volume they can vibrate my rear view mirrors to the point they distort and the tweeters hit every high you throw at them... this set is a very good buy!!!

Pyle Gear 6 1/2" Speaker Component Kit
For the price these speakers are great!!! yeah if you want to spend big bucks you could find something better, but this product gives you a lot of bang for your buck.

AMAZING DEAL!! GREAT SPEAKERS!
I didn't have a lot of cash to spend on speakers, so you better bet that I did my research before purchasing these. And man, did I make a good decision. The bass is AMAZING, and I don't even have an amp wired in, just running off my JVC head unit. I have not yet installed the tweeters, so I'm excited that there is still more to come. For under $50, you just can't beat it.

AWESOME MAGAZINE
I've been reading this magazine since it's birth and it is by far the most informative magazine out there. There are always excellent articles about cutting edge technologies and I find the content to be user friendly in day to day development.
Now that CoDe is focusing on the .NET/Microsoft technologies goes to show that this is the ONLY development magazine to keep around.

Excellent Articles from Concepts to Implementation Specifics
I've been reading this magazine since 2000, [the first issue I think] when it was very Visual FoxPro-centric. It has always presented excellent articles about cutting edge technologies, and presented development techniques that are useful in real world development environments.
The focus is now on the .NET/Microsoft technologies, and there is always something in each issue I can use to improve my skill set.

Awesome resource for .NET Programmers!
CoDe is really the best .NET mag out there today. While MSDN is often too technical and Visual Studio mag is often too "lite", CoDe gives good examples from programmers who know what they are doing. I highly recommend it!

audio cable adapter
Oh my. another cable adapter. This time we needed to get from a laptop to the TV. Works fine. Wouldn't it nice to have a combination firewire + audio cable? Our laptop does not have HDMI so this is the way we hooked up the computer to the TV. Cumbersome but not the cable's fault. Maybe a bluetooth interface between the laptop and TV would work better.

Dead cable
I bought this Belkin cable to send audio from my PC to my digital TV. It was delivered pretty fast... except that when I connected it from my PC to my TV, no sound. I tried a different computer, same result. My computers send audio to headsets without problem from the very same audio output port where I connected the Belkin cable.

It's not my TV either because my DVD player sends audio to the TV without problem through red and white jacks similar to the ones on the Belkin cable. I also tried an analog TV and still no sound.

Looks like the cable is defective and seeing it's more trouble sending it back, I am just gonna throw it away. Very disappointing.

Sturdy, Durable audio cable
I purchased this cable for use with an auxiliary input system in my 2002 Honda Civic. I can now listen to my Ipod on long drives and road trips!

The Cable itself is substantial and will not break or rip anytime soon. The thickness was perfect for a car instillation where additional shielding from other electronics in close proximity is essential. However, it is still thin enough to be plenty flexible for use in tight spaces. The connectors are sturdy and provide excellent connectivity.

This cable is perfect for any vehicular, home or other instillation. It works as advertised perfectly.

Didnt work for me
I probably didnt do something right but i got these along with a VGA cable to hook my laptop up to a tv.. couldnt get sound out of the tv with this cord. I just bought a hdmi cable instead of using this and the vga

Perfect...Just what I was looking for
I needed a longer cable and I was so glad I was able to find it online because I couldn't find it in the stores. I love Amazon!!!

I got a lemon
The fan blows a lot of air as it is supposed to. It is not silent but is not overly loud.
The unit I got seems not to be balanced properly, so there is a vibration added to my case (HAF922) as I am using it. If I hold it in my hand while it is running I also feel this vibration. No sense returning to amazon.

NOT 90CFM
NOT 90CFM. This fan is 69.9 CFM The R4 that is 90CFM is the R4-L2R-20CR-GP It's got a red LED...Don't know how to disconnect the lights.

nice fan.
nice fan. moves a respectable amount of air with little noise.. it's not silent by any means, but you will be adding a low-pitched 'wooooshing' sound to your system... tho this is a small price to pay for proper ventillation.

Great fan - wouldn't mind getting another
I got this to replace a fan that came with my case after the bearings seized up, and I have no regrets. It's no noisier than the original, but it moves a lot more air. My CPU temps dropped 5 degrees C from where they were before. It also has no annoying LEDs.

Very cool!!
Yes very cool on every level. The fans are great and have decreased my system temp by about 10 degrees C. System runs consistent at 30C now. They move a lot of air for sure, but they do make noise so if you're looking for a quiet system not the way to go. Since I am only concerned with performance it is perfect. When playing MP3s at normal levels the noise is not noticeable to me.

I'm very happy with the purchase.
