Freely downloadable. Entitled "A Closer Look at Instruction Set Architectures"
http://samples.jbpub.com/9781449600068/*00068_CH05_Null3e*.pdf looks interesting. Unfortunately, the book is $203. They have a epub version for $103, but it is somehow "time limited" to 360 days. I guess it somehow become unreadable after that. Too expensive for my limited budget. I was looking around to see what I could find regarding how actual computer architects logically design an ISA. I can't really find much. I would _love_ to know why the z designers created some of the instructions that exist. And then basically warn about their poor performance. -- Wasn't there something about a PASCAL programmer knowing the value of everything and the Wirth of nothing? Maranatha! <>< John McKown
