Abstract
PURPOSE: To efficiently transfer data by decoding an instruction transferred from a CPU by an interface circuit means and writing succeeding data in a prescribed area of a memory in accordance with its byte constitution based on the decoded result. CONSTITUTION: Data is transferred from a CPU 3 to an interface circuit means 6 in accordance with a variable format where data having a variable byte length constitution follows an instruction; and for the purpose of coping with this variable format, the instruction transferred from the CPU 3 to the interface circuit means 6 is decoded, and succeeding data is written in a prescribed area of a memory 7 in accordance with its byte constitution based on the decoded result. Thus, data is transferred from the CPU to the interface circuit means in accordance with the variable format adapted to byte length different by various data, and dummy data is eliminated, and a delay due to unnecessary instruction transfer doesn't occur, and data is transferred most efficiently.
