Abstract:
A low power consuming operating device for digital signal processing, comprising:external input means for receiving digital data, temporarily storing the digital data, and outputting the stored data;specified signal sensing means for determining whether the digital data received from the external input means is a specified input of which occurrence probability is greater than a predetermined value and outputting the determination result;internal input means for outputting the digital data except for the specified input received from the external input means, in response to the determination result;operating means for operating on the data output from the internal input means and temporarily storing the operating result; andexternal output means for selectively outputting either the temporarily stored output of the operating means or a value corresponding to the specified input, as the final operation result of the digital data, in response to the determination result wherein when said value is output said value is output without passing through the operating means.
