interrupting for overflow and loop termination Are there any CPU architectures which tie the overflow flag to an interrupt, so that programs don't have to put a flag test and conditional branch after each arithmetic operation in order to avoid modular arithmetic? And similarly, are there any architectures which tie the output of a logic function (hardwired or ... 28 Sep 2005 07:35
Multicores Does anyone have any thoughts on whether dual processors are worth building into a home computer or not? - Raven ----> For a fun time, check this out> http://ZeldereX.com/?topic=80844 ... 8 Sep 2005 20:24
Intel x86 memory model question The question isn't what is the x86 memory model. If you want to discuss that, you are welcome to join the fray on c.p.t. The question is why can't or why doesn't Intel want to document the x86 memory model since apparently what is in the System Programming Guide is *not* the memory model. I.e. not as far as pro... 14 Sep 2005 08:23
CPU <> Memory chip communication interface Hi, First I would like to program a simple CPU and Memory chip in pascal/delphi. (Maybe a better word for memory chip would be memory controller ?) The CPU and Memory chip communicatie in serial bits with each other. These serial bits could be commands/addressess which the memory chip can understand. I ... 30 Aug 2005 11:32
B8500 D825 Documents Does anyone have any B8500 or D825 documents? D-Machine? There was also a B8300 for a TWA(?) airline reservation system, anything out there about that? I am also interested in IRE Journal articles about AOSP (the 825 OS) and early Burroughs floating-point arithmetic. Thanks JKA -- "If you can't drink ... 6 Aug 2005 00:08
IBM 360/370 instruction set architecture Hi, Does anyone know any links for the IBM 360/370 instruction set architecture? I've been looking for it for a very looooong time but i've found no good site about it. I just need a list of instructions for 360/370, addressing modes and instruction formats. Please help me Adam ... 10 Jun 2005 20:47
Where is balance? -- Re: Academic priorities >I'd expect smoothness to be understood in college, maybe high school for the truly precious. I think its hard to understand what C infinity really is without a good course in math. OK smoothness, continuity and analyticity are all nice. BUT when do you start teaching people that functions with even C0 are th... 22 May 2005 18:19
The Case For Biquinary I recently acquired an IBM 650 manual, and I was interested to learn that it used a biquinary representation for integers. This is a decimal format, in which five bits represent the values 0-4 or 5-9 and two binary bits select between the upper and lower range of values. (In other biquinary formats, a single bi... 18 Apr 2005 16:39
big-edian & little-endian hi every body i wrote a c languge program ti determine ur machine whether big-edian or little-endian, and i tried it on my machine (little-endian machine), can any one please try it on big-edian machine and email me the result. thanx. here is the program: /********************************************************... 4 Mar 2005 14:32
Instruction Reduction Hello, Tanenbaum says in his Structured Computer Organization book that all instructions can be reduced to: 1. An addition operation 2. Check to see if a number is zero 3. Copy data from one memory location to another I was wondering if anyone can point me to a chart for instance, that shows such a reducti... 4 Mar 2005 07:49 |
