Bus bridge with a burst transfer mode bus and a single transfer mode bus

摘要

A computer system component (12) serves as a burst mode data transfer proxy for bridging a bus (8, 9, 20) operable in burst transfer mode and a single transfer mode bus (21). FIFOs (61), associated with respective DMA channels, provide a shared area for assembling and disassembling bursts on behalf of subsystems on the single transfer mode bus (21). The component (12) also performs DMA functions. <IMAGE>
