Says the Pentium memcpy patch:
+ This enables special routines for copying and zeroing chunks of + memory that use the FPU to move 64 bit chunks of memory, which is + otherwise not possible on the Pentium processor.
Says their Web page:
In order to increase write rate dramatically, we made the simple trick of using floating point writes, which are the only way 64 bit writes can be done on a non-MMX Pentium. ___ Trevor Johnson
