DCA Prefetch Delay
A DCA Prefetch is used with TOE components to prefetch data in order to shorten
execution cycles and maximize data processing effi ciency. Prefetching too fre-
quently can saturate the cache directory and delay necessary cache accesses. This
feature reduces or increases the frequency the system prefetches data. The options
are [8], [16], [32] , [40], [48], [56], [64], [72], [80], [88], [96], [104], [112], [120]
