Abstract
A bus bridge between a high speed DMA bus and a lower speed peripheral bus sets a threshold for minimum available buffer space to send a read request dependent upon a frequency ratio and the DMA read latency. Similarly, a threshold for minimum available data for a write request depends on the frequency ratio and the DMA write latency. The bus bridge can store programmable values for the DMA read latency and write latency.
