초록
Provided are an apparatus for controlling power management of a DSP (Digital Signal Processor) and a power management system and method using the same. The power management system includes a command decoding device for decoding a program into which a PSM (Power Saving Mode) command and a general command are inserted and transmitting module information required for execution of a corresponding command to a power management control apparatus at the time of decoding the corresponding command; a pipeline control device for blocking and restarting the transmission of data through a pipeline upon receipt of a pipeline control signal (pipeline stall) from the power management control device; and the power management control apparatus for controlling power in respective modules by setting/resetting corresponding bits of a PSM status register and a PSM flag register in accordance with the PSM command and the general command decoded in the command decoding device.
