DATA TEMPORARY STORAGE DEVICE AND CLOCK SYNCHRONOUS TYPE DATA PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide the data temporary storage device equipped with a selector function and provides the clock synchronous type data processor which uses the data temporary storage device equipped with the selector function. SOLUTION: The write state and data holding state of four input data are controlled by controlling master level latch control signal lines 1011-1014. The data temporary storage device can be constituted which has a 4-input, 2-output selector function for selecting two out of four inputs by controlling slave level latch control signal lines 1021-1024, and 1031-1034.
