PURPOSE:To enable easy addition of a new function to a multifunctional signal processing capacity by constituting a titled processor in such a way that plural sets of circuit constitution including a digital signal input terminal, a pulse generating part and a digital signal processing arithmetic part can be added. CONSTITUTION:An analog signal input part 2 is constituted of an amplifier of variable gains, an A/D converter, etc. An analog signal output part 7 is constituted of a D/A converter for D/A-converting digital data obtained by processing, etc. Circuits A and B have digital signal processing arithmetic parts 51 and 52, pulse generating parts 61 and 62 and selectors 41 and 42. When a processing function is transferred as a command from an external controller through a terminal 10, a control part 12 reads out programs for all functions to be executed in the digital signal processing arithmetic parts 51 and 52 and outputs them to a terminal 17. Thus multifunctional operation can be executed in parallel, and when a new operating function is added, a signal processing program ROM of the control part 12 may be added. |
