Method for chaining media processing

An embodiment of a system may include a plurality of media units, a processor, and circuitry. Each media unit may be configured to execute one or more commands to process a display image. The processor may be configured to store a plurality of media processing commands in a queue. The circuitry may be configured to retrieve a first media processing command from the queue and send the first media processing command to a first media unit. The circuitry may also be configured to retrieve a second media processing from the queue and send the second media processing command to a second media unit in response to receiving an interrupt from the first media unit. The circuitry may then copy data from the first media unit to the second media unit in response to receiving the interrupt from the first media unit. 本发明提供了种系统的实施方案可包括处理器、电路和多个媒体单元。每个媒体单元可被配置为执行用于处理显示图像的个或多个命令。处理器可被配置为将多个媒体处理命令存储在队列中。电路可被配置为从队列中检索第媒体处理命令并将第媒体处理命令发送至第媒体单元。电路还可被配置为响应于接收到来自第媒体单元的中断，从队列中检索第二媒体处理并将第二媒体处理命令发送至第二媒体单元。然后电路可响应于接收到来自第媒体单元的中断，将数据从第媒体单元
