Graphics processor, system variable generation method thereof and medium

The invention discloses a graphics processor, a system variable generation method thereof and a medium. The method comprises the following steps: storing a system variable reference value of data corresponding to a reference channel; the system variable reference value comprises a local reference identifier and a global reference identifier; acquiring the local reference identifier and the global reference identifier of the data corresponding to the reference channel; and based on the local reference identifier and the global reference identifier, generating a local target identifier and a global target identifier of the data corresponding to the target channel. By adopting the scheme, in the process of managing the system variables, the occupied on-chip resources are less, and the system performance is higher. 一种图形处理器及其系统变量生成方法、介质，所述方法包括：存储基准通道对应数据的系统变量基准值；所述系统变量基准值包括本地基准标识以及全局基准标识；获取基准通道对应数据的所述本地基准标识以及所述全局基准标识；基于所述本地基准标识及所述全局基准标识，生成目标通道对应数据的本地目标标识以及全局目标标识。采用上述方案，在管理系统变量的过程中，所需占用片内资源较少，且系统性能较高。
