Sample request mechanism for supplying a filtering engine

摘要

A graphics system comprising a scheduling network, a sample buffer and a plurality of filtering units. The sample buffer is configured to store sample generated by a rendering engine. The plurality of filtering units are coupled in a linear series. Each filtering unit of the linear series is configured to send a request for a scanline of sample bins to a first filtering unit of the linear series. The first filtering unit is configured to service the scanline requests by sending burst requests to a scheduling network and coordinating the flow of samples forming the bursts from the sample buffer to the filtering units.
