摘要：A system and method for efficiently performing a command swappingprocedure may preferably include a processor configured to generate commandscorresponding to various peripheral devices in an electronic system. A command queue
may receive the foregoing commands from the processor, and may responsively storethe commands into a FIFO memory device that may be configured to temporarily storethe commands in a series of sequential memory locations. The peripheral devices maythen repeatedly access the commands from a first location of the FIFO memory devicewhen the corresponding peripheral devices are ready to execute the commands. Swaplogic from the command queue may advantageously exchange a delayed commandcorresponding to a busy peripheral device, and substitute a non-delayed command for anon-busy peripheral device into the first location of the FIFO memory device to therebypermit the non-delayed command to be executed in a more expeditious and efficientmanner.
