ADL executable protocol-adopted ASIP design method

Abstract

The invention relates to a design method of a computer architecture structure, in particular to an ASIP architecture structure-oriented design method. The method mainly comprises the following steps of: firstly, selecting a typical open-source processor core, extracting system-level feature parameters after analyzing a specific application; determining specific values or forms to which the system-level feature parameters refer, and storing the system-level feature parameters into a feature parameter database; respectively establishing an ADL structure model and an ADL behavior model accordingto the feature parameters in the feature parameter database; and finally converting the established ADL models, verifying and optimizing the converted ADL models in third-party EDA environment, and logically and comprehensively downloading the ADL models into an SoC to be operated. The method follows a description-synthesis design methodology, and is capable of obtaining ASIP systems with the optimum comprehensive performance indexes through a chained process of application analysis-modeling description-design space exploration-synthesis-assessment-feedback.

Description

technical field [0001] The invention relates to a design method of a computer architecture, in particular to a design method for an ASIP (Application Specific Instruction Set Processor, application specific instruction set processor) architecture. Background technique [0002] Compared with ASIC (Application Specific Integrated Circuits, Application Specific Integrated Circuits) and GPP (General Purpose Processor, General Purpose Programmable Processor), ASIP applications achieve a satisfactory cost-effective balance between the two. It features user-defined instructions, data paths, and accelerators to maximize the use of limited hardware resources. This feature is more and more favored by embedded system technicians and has a good application prospect. ASIP can achieve a good balance between computing performance and energy consumption, making it the main choice for embedded processors. Its design methodology has moved from the development stage to the mature stage, and w...

Problems solved by technology

The existing technology is to design the above two parts separately, and the design method basically follows the GPP method, which cannot fully utilize the characteristics of application-oriented ASIP

[0004] At the system level, the existing design does not focus on the abstract modeling of the top-level system, mainly tailoring the GPP ISA and its logic modules; in terms of design methodology, the traditional design method of digital logic is still used instead of the "top-level system model". Behavior description→functional verification simulation→logic synthesis implementation” is a consistent optimization iterative process, and it does not make full use of EDA tool chain and SoC modern technology
