Description

technical field

[0001] The invention belongs to the technical field of computer hardware verification, and relates to a GPU performance simulation method and platform based on a SystemC TLM virtual prototype; in particular, it relates to a GPU chip-oriented host interface unit performance simulation method and platform. 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 Nvidia released the first GPU product in 1999, the development of GPU technology has mainly gone through the fixed performance 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 p...

Embodiment Construction

[0048] Now, the present invention is described in detail in conjunction with the accompanying drawings.

[0049] Propose a kind of performance emulation method facing GPU chip host interface unit in a fact example of the present invention, method comprises the following steps:

[0050] 1) Using SystemC language and transaction-level modeling TLM method, build a performance simulation platform for the GPU chip host interface unit;

[0051] 2) The host interface unit port conversion in the performance simulation platform only converts the external transaction level port into a hardware signal level port. Embed the host interface RTL unit into the host interface unit port translation;

[0052] 3) The input and output timing of the host interface RTL unit is collected through host interface unit port conversion, and the performance efficiency of the host interface RTL unit is counted to achieve the purpose of performance simulation verification of the host interface unit.
