Abstract:
An information processing system for performing a computational task, the system comprising:a processor for performing a first portion of the computational task;a co-processor for performing a remaining portion of the computational task;a system bus permitting the processor to command the co-processor to perform the remaining portion of the computational task by transferring a command block to the co-processor;the system bus providing an address phase transfer and a data phase transfer, and the address phase transfer having an upper address part and a lower address part;the co-processor being responsive to a co-processor selection address received on the upper address part for receiving the lower address part during the address phase transfer, and for receiving a data part during the data phase transfer;the command block including the co-processor selection address, a co-processor command code, and at least one co-processor command parameter; andthe processor using the lower address part and the data part to transfer the at least one command parameter.
