ABSTRACT:
A task processing apparatus includes a main CPU, a plurality of sub-CPUs, a first starting section, a second starting section, and a notification section. The plurality of sub-CPUs independently execute a series of difference tasks set in advance in accordance with a predetermined sequence. The first starting section is arranged in the main CPU to output a first starting signal for starting the first sub-CPU, of the plurality of sub-CPUs, which executes a first task at the start of the series of tasks. The second starting section is arranged in each of the sub-CPUs except for the last sub-CPU. When the task in a given sub-CPU is completed, the second starting section outputs a second starting signal for starting the next sub-CPU which executes the next task. The notification section is arranged in the last sub-CPU of the plurality of sub-CPUs. The notification section supplies a processing completion signal indicating completion of the series of tasks to the main CPU when the last task is completed.
