<p>PROBLEM TO BE SOLVED: To provide an integrated circuit for incorporating a digital signal processor(DSP) or the like that can reduce the noise. SOLUTION: The integrated circuit provided with the DSP and a plurality of processing blocks connected to the DSP is provided with a data transmission line changeover means 180 that sets a data transmission line between processing blocks for selected processing, data transmission line opening means 112, 122, 132, 142, 152 that disconnect picture blocks not connected by data transmission lines 181-189 set by the switching of the data transmission line changeover means 180, and clock supply path cut means 113, 123, 133, 143, 153 that disconnect a clock supply path 171 to processing blocks not connected to the data transmission lines set by the switching by the data transmission line changeover means 180.</p> |
