Abstract

the bus contention among bus-based shared-memory multiprocessors limits their performance. In addition under split bus transaction environment, multiprocessors may make some memory requests unnecessary stand by in the memory access buffer, which makes system performance worse. This unnecessary stand-by can be eliminated by maintaining bitmap table which contains the status bit for each memory block. However, this mechanism requires a great size of SRAM for the status information, which is fully mapped from the whole memory blocks. To solve this problem, we propose a bitmap cache which exploits partial mapping and locality of references. The simulation results show that the proposed system can greatly reduce the capacity of SRAM for the status information with little deterioration its performance.
