Abstract
A data processing apparatus has a latch circuit between a processing unit and a memory. Processed data produced by the processing unit is not directly written into a working area of the memory, but is temporarily stored in the latch circuit. A write operation of the processed data stored in the latch circuit is executed in parallel with a read operation for reading the next data to be processed out of the memory and/or an executing operation of the processing unit. Therefore, processing speed is much improved. In addition, the processed data in the latch circuit can be directly transferred to the processing unit without first having to be written into the memory.
