Method and apparatus for improved double buffering

摘要: A method and apparatus for improved double buffering within a computing system begins when series of data blocks are received from central processing unit at rate independent recipient engine. For example, video graphics circuit receives representing frames the refresh display. As received, queues commands blocks. Typically, include synchronize command. To process blocks, co-processor pulls queued list processes them to produce data. is producing data, it utilizing first buffer. The continues storing results into buffer until command detected. At this point, pauses commands. beginning next cycle rate, provided engine resumes commands, which relate another block. second block, store processed i.e.,
