Abstract

The invention relates to the technical field of computer hardware verification, in particular to a graphic pipeline unit function simulation method and platform for a graphic processing unit (GPU) chip. According to the method, a graphic processing unit (GPU) chip TLM virtual prototype platform based on SystemC is established (the virtual prototype verification platform comprises a host, an ROM, adisplay, DDR0, DDR1 and a GPU); a TLM transaction level port of a GPU graphic pipeline unit is converted into a hardware signal level port, an RTL code of the graphic pipeline unit is embedded into aTLM virtual prototype platform, and module level and system level function simulation is carried out on the RTL of the GPU. Therefore, the problem that the behaviors of the GPU module-level RTL simulation environment model and the GPU system-level RTL simulation environment model are not unified is solved through the TLM virtual prototype platform, the reusability of the simulation environment isimproved, and the development and verification work of the GPU chip RTL is accelerated.

Description

technical field [0001] The invention relates to the technical field of computer hardware verification, in particular to a GPU function simulation platform based on a SystemC TLM virtual prototype. Background technique [0002] With the continuous increase of graphics applications, the early solution of graphics rendering by CPU alone has been difficult to meet the graphics processing needs of performance and technology growth, and the graphics processing unit (Graphic Processing Unit, GPU) came into being. Since the release of the first GPU product by Nvidia in 1999, the development of GPU technology has mainly gone through the fixed-function pipeline stage, the stage of separating the dyer architecture, and the stage of unified dyer architecture. Rendering gradually extends to the field of general computing. The high-speed, parallel features and flexible programmability of the GPU pipeline provide a good operating platform for graphics processing and general parallel compu...
