80960CF Processor Overview
Intel’s 80960CF is the second processor in the series of superscalar i960 microprocessors that also
includes the 80960CA and the 80960HA/HD/HT. Upgrading from the 80960CA to the 80960CF is
straightforward because the two processors are socket- and object code-compatible.
As shown in
(80960CA instruction cache is 1 Kbyte; it does not have a data cache.) This extra cache on the CF
adds a significant performance boost over the CA.
