Cache Write Generate for high performance parallel processing

Summary form only given. Generate, a new cache write handling scheme that avoids unnecessary reads from main memory, reduces bus contention, and increases the available bandwidth of the memory, is presented. Cache Write Generate increases the amount of CPU execution and memory load/store overlap, and decreases the memory cycle time. The performance of cache write generate is compared with that of write around and write allocate in single processor and shared bus multiprocessors and demonstrate a speedup of 1.2 to 1.5 over allocate and write around.
