Switching sample buffer context in response to sample requests for real-time sample filtering and video generation

摘要

A graphics system configured with a scheduling network, a sample buffer, a rendering engine and a filtering engine. The rendering engine is configured to generate samples in response to received graphics data, and to forward the samples to the scheduling network for storage in the sample buffer. The filtering engine is configured to send a request for samples to the scheduling network. The scheduling network is configured to compare a video set designation of the request to a previous request designation, to update one or more state registers in one or more memory devices of the sample buffer in response to a determination that the video set designation of the request is different from the previous request designation, and to assert signals inducing a transfer of a collection of samples corresponding to the request from the one or more memory devices to the filtering engine.
