This document discusses the functionality and performance of an asynchronous memory interface developed for ADSP-BF531 / BF532 / BF533 Blackfin® processors. The interface is designed to provide a host port-like interface in applications that require a Blackfin processor to be used in conjunction with a host microcontroller. It can also be used to connect two Blackfin processors with minimal external circuitry. The maximum throughput of this implementation is 14.8 MB/s without concurrent bus activity and 8.3 MB/s while concurrent DMA activity is taking place. (e.g., simultaneous peripheral and memory DMA). Higher bandwidth interfacing can be achieved with additional external logic.
