   The killer thing is that the vector processing unit only handles
32 bit IEEE FP numbers...

Mersenne: TMS XP-15 DSP card

2002-02-13 Thread George Pantazopoulos

Hey all,
This XP-15 ( http://www.superdsp.com/ ) bad boy DSP card looks pretty 
impressive, how useful would it be in searching for Mersenne primes? At 
$14,000 a pop, how would it compare to a farm of P4's? According to the 
Presentation pdf, it is 42 times as fast as a 1.4GHz P4 at a 1024K FFT!

Regards,
George Pantazopoulos
