Abstract
PURPOSE:To reduce the number of steps necessary for repeated processing of product sum operation or the like by simultaneously supplying new read data and an arithmetic result stored in a writing data latch to an arithmetic logical operation unit. CONSTITUTION:A write data latch (WDL) for holding write data is formed in a RAM and an input route for inputting the write data stored in the WDL to a specified address of a memory array M-ARY and an output route for outputting the write data stored in the WDL as it is to a prescribed data bus out of data buses DB-A-DB-C are formed. Thereby, the read new data and the arithmetic result stored in the WDL can be simultaneously supplied to the arithmetic logical operation unit (ALU). Consequently, the number of steps necessary for the arithmetic processing can be reduced and the processing performance of microprocessor or the like including the RAM can be improved.
