Abstract
PURPOSE:To reduce the number of access of the main memory and to speed up the processing speed, by constituting the operation circuit with the circuit converting parallel one word picked up from the main memory, temporary memory of 1-bit x n words memorizing the output, and the circuit converting the output into parallel one word etc. CONSTITUTION:The output of the main memory 1 is connected to the parallel serial conversion circuit 5 via the output bus 10, and the circuit 5 converts the word information of parallel plurality bit into serial word information. Next, the output of the circuit 5 is fed to the temporary memory 6 and the processing speed is quickened by selecting the data faster in the access time in comparison with the main memory 1. To this memory 6, the function memorizing the data from the circuit 5 as well as the output from the one-bit operation circuit 2 is given. After that, the output of the memory 6 is connected to the serial parallel conversion circuit 7 and the circuit 2, the circuit 7 converts the serial data from the memory 6 into the word information of parallel plurality bit, and the information is written in the memory 1 via the input bus 11.
