<p>PURPOSE:To provide the circuit constitution and the control circuit where the. power consumption of the whole of the circuit is reduced without complicating the circuit of a control part. CONSTITUTION:An instruction set given to the whole of the circuit is analyzed by a control part 4, and a control signal to realize the instruction set is outputted to circuit resources 11 to 13 of a circuit resource group 1 and a decoder 3. Since the signal decoded in the decoder 3 corresponds to each circuit resource in the circuit resource group 1 in 1:1 and only one is selected from circuit resources in the circuit resource group 1, and therefore, it is unnecessary to operate circuit resources in the circuit resource group 1, which are not selected by the decoder 3, except the write operation to the RAM 11.</p> |
