THis was one of the more expensive books I bought for info on the ARM architectures, but I'm disappointed, the book covers just the core ARM architecture and is a few years out of date now too. Its a tough book to write, no doubt, there are so many variations on ARM that its unrealistic to expect them all to be coevered, but I'd like to have seen some more specifics. Most ARM imlementations by the multiple vendors ot there put in a bunch of peripherals, I'd like to have seen some attemtp to address those features better.
If you wanted a detailed ARM core reference, it might be the book for you, but bear in mind it doesn;t addres the newer products...
