System and method for efficiently performing a command swapping procedure

摘要

A system and method for efficiently performing a command swapping procedure may preferably include a processor configured to generate commands corresponding to various peripheral devices in an electronic system. A command queue may receive the foregoing commands from the processor, and may responsively store the commands into a FIFO memory device that may be configured to temporarily store the commands in a series of sequential memory locations. The peripheral devices may then repeatedly access the commands from a first location of the FIFO memory device when the corresponding peripheral devices are ready to execute the commands. Swap logic from the command queue may advantageously exchange a delayed command corresponding to a busy peripheral device, and substitute a non-delayed command for a non-busy peripheral device into the first location of the FIFO memory device to thereby permit the non-delayed command to be executed in a more expeditious and efficient manner.
