PURPOSE:To store information of a long time without increasing memory capacity, by compressing a multiple of period information into a career information memory in one period. CONSTITUTION:An asynchronous signal 1 is branched into two; one signal 1-2 is inputted to a logical sum circuit 5 and another signal 1-1 is inputted to the set of a latch circuit 4, and the output of the latch circuit 4 is inputted to a logical sum circuit 5. The output of the logical sum circuit 5 is inputted to a register 2, and the output of the register 2 is inputted to a carrer information memory 3. The write-in period for the reset of the circuit 4, renewal of register 2 and career information memory 3 are respectively 4r and the set signal for the latch circuit 4 is made for every r. |
