Abstract: A graphics processing system includes a decision logic and a varying buffer control circuit. The decision logic sets a control signal by checking at least one criterion, wherein the at least one criterion includes a first criterion, and a checking result of the first criterion depends on a size of a primitive. The varying buffer control circuit refers to the control signal to determine whether to store varying variables of the primitive into a varying buffer.

Abstract: A graphic processing circuit with binning rendering and associated pre-depth processing method is provided. Firstly, a first depth data of a first primitive corresponding to a specified tile is received. Then, the pre-depth data corresponding to the specified tile is read from a pre-Z buffer. If the first depth data is not larger than the pre-depth data and the first primitive is an opaque primitive, the pre-depth data is updated with the first depth data. If the first depth data is not larger than the pre-depth data and the first primitive is a translucent primitive, an uncertainty ordering range is defined according to the first depth data and the pre-depth data, and the pre-depth data is updated with the uncertainty ordering range.

Abstract translation: 提供了具有binning渲染和相关的预深度处理方法的图形处理电路。 首先，接收对应于指定瓦片的第一原语的第一深度数据。 然后，从预Z缓冲器读取对应于指定瓦片的预深度数据。 如果第一深度数据不大于预深度数据，并且第一原语是不透明原语，则用第一深度数据更新预深度数据。 如果第一深度数据不大于预深度数据，并且第一图元是半透明图元，则根据第一深度数据和预深度数据来定义不确定性排序范围，并且更新预深度数据 具有不确定性排序范围。
