Abstract: PROBLEM TO BE SOLVED: To provide a data processing unit which has a coupling unit for data transfer. SOLUTION: This data processing unit is provided with a register file 8 having plural registers, a memory having plural n-bit input/output ports, a coupling unit for connecting the memory to the register file and a memory address and a selection unit 9 for addressing a memory bank. The coupling unit includes at least a bus which forms 1st and 2nd sub buses and has at least 2n-bit bus width, a 1st coupler for selectively connecting each memory bank or register file to one of the sub buses and a 2nd coupler for connecting the register file or a memory bank to the buses.

Abstract: The method involves using a command localization indicator relating to a forthcoming command, to identify a next-data-prefetch indicator. The memory planes (60,64,68) are searched to find data relating to the next-data-prefetch indicator. These data are then transferred to the low-plane memory of the computer system. An apparatus for data prefetch is also claimed.
