Abstract
PURPOSE:To increase the working speed and the hardware quantity of a processor by using a 1st cache memory for access of operands and branch instructions and a 2nd cache memory for access of instructions. CONSTITUTION:A instruction is prefetched by an instruction address stored in an advance instruction address register 7 in parallel with execution of an instruction carried out by an instruction execution control part 12. A logical address of the register 7 is converted into a real address by an instruction address converting buffer 9. This real address gives an access to a 2nd cache memory 4. The contents of the register 7 are replaced by a counter with an instruction access request and the next instruction access address is shown. At the same time, an operand address is produced by an operand address production circuit 10 and converted into a real address by an operand address converting buffer 11. Then an access is given to the 1st cache memory 3.
