ABSTRACT:
A time-shared multitask execution device processes two or more tasks in time-shared manner by using one CPU. A common set of a control register group and a queue selection control part are provided for plural task execution queue for executing plural tasks. Under the control of the control register group and queue selection control part, one CPU is occupied by the plural task execution queues in a time-shared manner, so that the plural tasks may be processed concurrently. The user has only to set the information necessary for the register in the control register group according to the user's specification, and the task execution specification can be determined. Therefore, even in the case of a user with a limited knowledge about the program, the desired specification can be set only by setting a flag bit of information to 1 or 0 in a register which is a part of the "hardware".
