Abstract

A memory look-up method, which uses one instruction buffer execution device, one control device and one data register to output one look-up data stored in one memory to the data register, comprises of: (1) in one first clock period, the instruction buffer execution device executes stored instruction ahead, generating one look-up signal output, and the control device responds the look-up signal to output next instruction stored in the memory to the instruction buffer execution device; and (2) in one second clock period, the control device generates one prohibit signal to latch the next instruction located in the instruction buffer execution device, and the control device generates and outputs one write instruction to the instruction buffer execution device for generating one write signal, therefore outputs the look-up data to the data register.
