In this paper, a multitask support proccessor (MTSP) element 1 is connected to the system through a master CPU and an internal bus similarly to the other peripheral input element 4.
Abstract: 
PURPOSE:To enable all CPUs to be applied to a microcomputer multitask control system by controlling the execution of a task in accordance with a command generated from a unit other than the CPU. CONSTITUTION:A multitask support proccessor (MTSP) element 1 is connected to the system through a master CPU2 and an internal bus 3 similarly to the other peripheral input element 4. A program memory 5 programs an initializing program of the MTSP element 1 and plural tasks independently and is constituted by connecting a memory 6 as a data memory to be used by respective tasks. The MTSP element 1 is provided with a task scheduling function for attaining the multitask system, synchronizing and communicating functions of tasks, a memory controlling function, a clock function, etc. An access from the CPU2 to the MTSP element 1 is executed by a command and an access from the MTSP element 1 to the CPU2 is executed by interruption.
