Embodiment Construction

[0047] Concrete, technical solution of the present invention is:

[0048] A GPU performance verification platform based on SystemC TLM virtual prototype, using SystemC language and TLM (Transaction Level Modeling, transaction level modeling) method, the hardware structure and function of GPU (Graph Process Unit, graphics processing unit) chip modeling;

[0049] The described GPU performance verification platform based on the SystemC TLM virtual prototype includes HIU, graphics pipeline unit, AXI bus crossbar, display control unit, DDR controller 0 and DDR controller 1 modules;

[0050] Described HIU module realizes that the OpenGL function order from mainframe Host is parsed and classified as graphics drawing command, graphics function command and graphics register resource access command, and these three types of commands are sent to the graphics pipeline unit module;

[0051] The HIU module realizes that the graphics data from the host Host is delivered to the graphics pipe...

Abstract

The invention relates to the technical field of computer hardware verification, in particular to a GPU chip-oriented graphic pipeline unit performance verification method and a platform. According tothe 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, a display, DDR0,DDR1 and a GPU); a TLM transaction level port of a GPU graphic pipeline unit is converted into a hardware signal level port. By embedding the RTL code of the graphic pipeline unit into a TLM virtualprototype platform, and performing module-level and system-level function simulation on the RTL of the GPU to verify whether the RTL of the graphic pipeline unit meets the performance index of the corresponding model or not, whether the performance of the GPU graphic pipeline unit meets the requirement or not can be verified in advance before the FPGA stage, and the development and verification work of a GPU chip in the follow-up stage is accelerated.

Description

technical field [0001] The invention relates to the technical field of computer hardware verification, in particular to a GPU performance verification 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 ...
