Problems solved by technology

Due to the wide range of computing-intensive applications, and the amount of computing of various applications is extremely unbalanced, it is difficult to use a unified VLIW structure to handle various applications
That is to say, in the prior art, using a single VLIW architecture cannot resolve the inherent conflict between the architecture and the application

Embodiment Construction

[0038] The main purpose of the present invention is to optimize the VLIW architecture of the prior art to overcome the disadvantage that a VLIW processor with a single architecture cannot be applied to multiple complex and intensive computing applications. The present invention proposes a structural realization of VLIW. Based on this structure, an application-optimized VLIW structure can be designed to solve the inherent conflict between the VLIW system structure and applications. The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0039]The core idea of ​​the VLIW architecture is to provide instruction-level parallel computing capabilities. However, due to the limitations of the architecture, any fixed architecture cannot meet the needs of different algorithms. Only variable parallel computing capabilities and variable registers can be provided. Access capability and variable-length VLIW instructi...

Abstract

The invention provides a very-long instruction word processor. The VLIW processor provided by the invention adopts data processing units with uniform interfaces and control modes, is provided with a distributed register file and a data exchange network, adopts VLIW instruction set per se with variable length, and has the capacity of randomly increasing or deleting the data processing units as application required from the application so that a designer can design the VLIW processor facing application according to the architecture of the VLIW processor provided by the invention, and the contradiction that the VLIW processor with a single structure cannot be applied to multiple application demands is avoided.

Description

technical field [0001] The invention relates to the technical field of processors, in particular to a very long instruction word (VLIW, Very Long Instruction Word) processor. Background technique [0002] Computer architecture refers to those processor system attributes visible to programmers, including programming ideas and hardware architecture. The definition of "computer architecture" was proposed by C.M.Amdahl in 1964 when he introduced the IBM360 system. ". [0003] Complex Instruction Set Computer (CISC, Complex Instruction Set Computer) and Reduced Instruction Set Computer (RISC, Reduced Instruction Set Computer) are two architectures of CPU. Their difference lies in different CPU design concepts and methods. The early CPUs were all CISC architectures, which were designed to use the least amount of machine language instructions to complete the required computing tasks. [0004] Since the birth of computers, people have been using the CISC instruction set method. ...
