Abstract
A method, an apparatus, and a computer program product for optimising a bus in a Processor Local Bus (PLB) system are disclosed. A master engine performs a transfer transaction of N bytes of data on the bus of the PLB system. A type of read or write data transfer to be performed by the master engine is determined to optimize operation of the bus in response to a transfer request received asynchronously from a device coupled to the bus. This involves a request type determination function. Data is asynchronously transferred using a FIFO between the device and the bus dependent upon the determined type of transfer.
