A GPU software and hardware interaction TLM system based on SystemC

Abstract

The invention relates to the technical field of computer hardware modeling, in particular to a GPU software and hardware interaction TLM model based on SystemC. The GPU software and hardware interaction TLM model based on SystemC comprises a host agent layer model and a host interface layer model, wherein the host agent layer model provides an interaction path between a software driver and the host interface layer model; wherein the host interface layer model provides an interaction path between the host agent layer model and the GPU hardware TLM model, and the interaction content comprises issuing of an OpenGL CM command packet, reading and writing of an architecture register, interruption processing and image and texture data loading or acquisition. The GPU software and hardware model interaction method based on the TLM model is achieved, the problem of software drive and hardware model interaction in GPU modeling is solved, and RTL design development and verification are effectivelyfacilitated.

Description

technical field [0001] The invention relates to the technical field of computer hardware modeling, in particular to a SystemC-based GPU software-hardware interactive TLM system. Background technique [0002] At present, my country is independently developing domestically produced graphics processor chips (Graphic Processing Unit, GPU). However, since domestically imported commercial or military GPU chips have been used in China before, there is a lack of design experience in GPU independent development. At the stage of technology exploration and development, at the same time, the scale of GPU chip hardware logic is huge. From the writing of system architecture documents to the realization of rtl design, this will be a long project, and even after the completion of rtl design, the verification of functional performance will require A lot of time, therefore, in order to improve the progress and reliability of self-developed graphics processor projects, there is an urgent need fo...

[0002] At present, my country is independently developing domestically produced graphics processor chips (Graphic Processing Unit, GPU). However, since domestically imported commercial or military GPU chips have been used in China before, there is a lack of design experience in GPU independent development. At the stage of technology exploration and development, at the same time, the scale of GPU chip hardware logic is huge. From the writing of system architecture documents to the realization of rtl design, this will be a long project, and even after the completion of rtl design, the verification of functional performance will require A lot of time, therefore, in order to improve the progress and reliability of self-developed graphics processor projects, there is an urgent need for a university method that can shorten the entire design cycle and assist the design process of graphics processors. This method is (Transaction Level Modeling , TLM) transaction-level modeling
