Message passing method for computer system

摘要

A message passing method for computer system is proposed. The computer system comprises a common device driver unit and at least one application module unit communicated to the common device driver unit through a message exchange unit. The message exchange unit is composed of a plurality of message buffers in a plurality of tasks. Each task has an independent message buffer pointed to another task and each independent message buffer is connected to two specific tasks only. The message passed in this computer system has a lead-code, a sub-code and an extend data. The lead-code comprises a command trigger sign and a ready sign.
