ABSTRACT:
A method and apparatus is provided for use in an asynchronous bus interface capable of multiple or single width transfers and controlled by handshake signals, in which the bus transaction may include multiple successive data transfers delineated by a data strobe, and in which each data transfer is terminated by a data handshake signal, and in which data transfers for different cycle types incur different propagation delays, including bus buffering apparatus for directing transfers over single and multiple width busses, and an asynchronous bus controller for returning data handshake signals with individualized timing characteristics in response to the master data strobe and the cycle type of the transaction, such that each successive data transfer is completed in the minimum time that propagation delays, as indicated by the cycle type, will allow, in order to maximize bus throughput.
