ABSTRACT:
This invention provides a a ROM (10) which stores circuit function definition data for defining specified logic circuits relating to electric discharge machining and a programmable IC (20) which defines a specified logic circuit according to the circuit function definition data. This configuration is cost effective and minimizes hardware space requirements compared with configurations which used different logic circuits combined together. Further, when hardware needs to be reconfigured, the change can be achieved easily by replacing ROM (10) only.
