PURPOSE:To provide a signal processing system capable of efficiently operating a microcomputer processing the conversion data from an A/D converter. CONSTITUTION:The first timer interruption routine Ia executed in response to the first interruption signal outputs an A/D conversion start command signal to an A/D converter and is completed without waiting the conversion work. The second timer interruption routine Ib executed in response to the second interruption signal is executed after the completion of the A/D conversion work and performs the calculation based on the digital conversion data. The period until the start of the second timer interruption routine Ib after the completion of the first timer interruption routine Ia is not spent to wait for the A/D conversion work, but it is spent for executing another program. |
