Abstract
Method and apparatus for high speed parallel transfer of bursts of data between a device and an external interface bus. A burst mode asynchronous protocol is utilized, in which synchronous bursts of data using DATA VALID signals are followed by an asynchronous handshake using an ACKNOWLEDGE signal. The apparatus includes a burst register for storing and transmitting the data words in a burst, and control logic responsive to DATA VALID and ACKNOWLEDGE signals and providing control signals to operate the burst register.
