PREFETCH/PREFETCHW *
Note:
* The AMD-K6-2 and AMD-K6-
III
processors execute the PREFETCHW instruction identically to the PREFETCH instruction.
On the AMD Athlon processor, PREFETCHW can increase performance by providing a hint to the processor of an intent to
modify the cache line.
Faster entry/exit of the MMX
or floating-point state
Prefetch at least a 32-byte line into L1 data cache (Dcache)
