- And what exactly disqualifies the DSP as a general purpose computer?
- It has a memory, a CPU, and I believe enough instructions to make it
- capable of universal computation. Therefore, it can run any program
- that your main CPU can run albeit in DSP assembler versus your processor's
- assembler. It's about the neatest thing about the falcon... Alas in a year
- or so everyone is going to have them and from the stats on the 56001
- in the Falcon garnered from comp.dsp, they'll have a better one...
- FYI Apple and Commodore will be putting in the AT&T DSP3210 chip into
- their computers. It has full floating-point support and both address and data
- bus are 32 bit. The 56001 has only integer instructions built-in and
- I believe a 16 bit databus and 24 bit address bus... I also believe that
- the price of DSP boards is probably about to plummet for everybody...
- I'd wait and see what people manage to make them do before you make
- any conclusions about their capabilities... I think one could put
- together a really nifty pipelined graphics co-processor with a couple
- of them....
-
- It's going to be a good year for computers. I'd advise anyone ready to
- upgrade to wait and see what everyone releases this year...
