Abstract: PROBLEM TO BE SOLVED: To improve the processing efficiency of data transfer in a computer system using plural bus systems for sending comparatively short message data. SOLUTION: The computer system includes a host processor 16 connected to a memory sub-system 10 through a 1st bus system, a controller and a 2nd bus system. The controller 18 includes a memory 26 for storing plural scripts to be reproduced for the processor 16 through the 2nd bus system. The script means an instruction set to be used for executing operation on the controller 18. Each script includes one or plural addresses so as to detect a message or state data (or other operation data) to be inserted before dispatching the script.

Abstract: A computing system that incorporates the invention includes a host processor which is coupled to a memory subsystem via a first bus system, a controller device and a second bus system. The controller device includes memory for storing plural Scripts for replay to the host processor, for instance, via the second bus system. A Script is an instruction set used to execute operations on a controller device. Each Script includes one or more addresses where either message or status data (or other operational data) can be found which is to be inserted, prior to dispatch of the Script. During operation of the computing system, the memory subsystem is caused, as a result of its operation, to issue an instruction to the controller device to dispatch a Script to, for instance, the host processor. The controller device responds by accessing the required Script, playing the Script which results in accesses to locally stored operational data for inclusion into the Script. Local storage of this data avoids unnecessary data transfers over the bus system to the memory subsystem to obtain the required data for inclusion into a Script.
