Abstract
A plurality of data items are received in each frame period, and a digital signal processor (DSP) checks a flag corresponding to each data item in each frame period before the DSP applies processing to the received data. When the checked flag allows the corresponding data item to be processed, the process is performed. When the execution of the process is finished, the flag is reset. When all the flags are reset, the DSP enters a sleep state.
