Abstract

The invention belongs to the technical field of computer hardware verification, and particularly relates to a GPU chip-oriented host interface unit function simulation method and a GPU chip-oriented host interface unit function simulation platform. TLM modeling is carried out on functions of the GPU by adopting SystemC according to module division, and TLM modules of any scale and any level in theGPU can be replaced with RTL codes, so that an RTL module simulation platform of the GPU can reuse a GPU virtual prototype platform; TLM modeling is carried out on the functions of the GPU by adopting SystemC according to module division, and the whole TLM model of the GPU can be replaced with RTL codes, so that an RTL system simulation platform of the GPU reuses a GPU virtual prototype platform.According to the method and the platform, coordination of work among software personnel, hardware module RTL developers and simulation verification personnel is facilitated, and unnecessary iterationis reduced.

Description

technical field [0001] The invention belongs to the technical field of computer hardware verification, and in particular relates to a function simulation method and platform for a host interface unit of a GPU chip. 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 gene...
