Abstract: A time counting control system comprises: a timing signal generator for generating at least a read-in clock signal on the basis of a reference clock signal outputted from a reference clock signal oscillator; a microprogram control unit including an address register which is controlled by the read-in clock signal outputted from the timing signal generator, an address section which decodes the contents of the address register and energizes address lines related to a plurality of processing steps, and a microprogram storing section which simultaneously outputs microprogrammed instructions and the address of the instruction to be succeedingly executed; and a count/operation unit which performs a counting operation under the control by instructions successively outputted from the microprogram storing section of the program control unit, includes an arithmetic device and a register connected to said arithmetic means to store counting information and is so controlled as to perform a counting operation each time the microprogram control unit processes the plurality of processing steps.
