Method, device and computer storage medium for verifying shader function

Abstract

The embodiment of the invention discloses a method and device for verifying a shader function and a computer storage medium. The method can comprise the following steps: running a first shader function through a first shader in front of a slice shader in a graphic rendering pipeline in a GPU for pre-prepared original data for shader function operation; capturing an operation result of the first shader function through a GPU after the operation of the first shader function is completed, and transmitting the operation result to a set cache; simulating and operating the first shader function through a CPU according to the original data, and obtaining a simulation result of the first shader function; reading an operation result of the first shader function in a set cache through a CPU; and comparing, by a CPU, an operation result of the first shader function with a simulation result of the first shader function to verify the first shader function.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of Graphic Processing Unit (GPU), and in particular, to a method, device and computer storage medium for verifying shader functions. Background technique [0002] Currently, in the graphics rendering pipeline, shader Shader functions can be written in a shader language (SL, Shader Language) to implement shader programs of various types of shaders in the graphics rendering pipeline. Since the Shader function runs on the GPU, the verification of the Shader function is more complicated based on the difference in the storage and compilation environment between the CPU and the GPU. [0003] Generally speaking, the current verification scheme for the Shader function is to encapsulate or analyze the final output data of the graphics rendering pipeline, so as to judge whether the execution result of the Shader function used in the processing of the graphics rendering pipeline is correct. In th...

The above scheme must be executed after the entire graphics rendering pipeline is executed before the output data can be parsed, resulting in many pipeline levels during verification and low verification efficiency
