Abstract:
A data processing device comprising:input means for inputting a digital signal to be processed;an output terminal for outputting a pulse signal;a digital microcomputer for receiving the digital signal from said input means, processing the received digital signal to generate a pulse signal having a duration length corresponding to a processing result, and supplying the generated pulse signal to said output terminal, said digital microcomputer including a read only memory for storing process steps; andan integrating circuit for integrating the pulse signal from said output terminal so as to form an analog signal for controlling operation of a device,wherein said digital microcomputer executes the stored process steps to (1) input a digital signal at a predetermined timing, (2) determine a value of the input digital signal, (3) store the determined value as an analog value, (4) output, at a predetermined timing, the pulse signal having a duration length corresponding to the stored analog value, and (5) repeat steps 1-4 in order to process a next digital signal.
