Abstract
PURPOSE: To improve the buffering effect of the buffer register of an information processing unit by detecting an empty quantity of the buffer register and by performing feedback control of an address adder to adjust data width to be fetched into the register.
CONSTITUTION: An address of address incrementer AI is increased by instruction address control part IAC and is transferred to instruction address register IAR through latch circuit AL to access odd and even memory units BMO and BME of buffer memory unit BM. Read data is transferred to instruction register REG through instruction buffer registers IBR.B and ABR.A. The empty state of these registers IBR.A and IBR.B is detected by instruction buffer control part IBC, and feedback control of incrementer AI is performed through control part IAC, and increment of the address is changed according to the empty state to adjust data width to be fetched into the register. As the result, the buffering effect of the buffer register of the processing unit is improved.
