Very long instruction word processor structure supporting simultaneous multithreading

Abstract

The invention provides a very long instruction word processor structure supporting simultaneous multithreading, which comprises at least two parallel instruction processing pipeline structures, wherein each instruction processing pipeline structure comprises an instruction obtaining module, an instruction distribution module and an instruction executing module, a general register file, a floating point register file and a control register file, the instruction obtaining module is used for obtaining instruction information, the instruction distribution module is used for receiving and distributing the instruction information obtained by the instruction obtaining module, and the instruction executing module comprises instruction executing units A, D, M and F which are used for executing the instruction information, the general register file is used for storing executing results of the corresponding executing units A, M and D, and the floating point register file is used for storing executing results of the corresponding executing units D and F. Through the structure, the resources of a processor can be more sufficiently utilized, the threading access efficiency is enhanced, and the processing speed of the processor is improved.

Description

technical field [0001] The invention relates to the technical fields of computers and electronic equipment, in particular to a super long instruction word processor structure supporting simultaneous multithreading. Background technique [0002] A microprocessor is a semiconductor integrated circuit integrated on a chip, including the control and execution of a series of arithmetic and logic operations. There are three common approaches to optimization of modern processor designs: [0003] 1. Increase the main frequency of the processor and shorten the execution time of each instruction. [0004] 2. Optimize the compiler and use more efficient instructions. [0005] 3. Instruction-level parallel technology (ILP). [0006] Since the higher performance of the processor cannot be solved from the traditional structure, various strategies for improving the performance have been proposed. Among them, the effect of increasing the clock frequency and compiler optimization is limi...
