Abstract: <P>PROBLEM TO BE SOLVED: To easily suppress the variation of a power supply voltage caused by a difference in a power consumption state by a circuit synchronized with a clock cycle.  <P>SOLUTION: A current consumption circuit (20) that performs a current consumption operation is adopted when a first circuit (2) being operated in synchronization with the clock cycle and capable of requesting an access, waits for a response to the access request. To suppress the reduction of a consumed current amount in an operation suspension period instructed by the first circuit, the current consumption circuit performs the current consumption operation in each clock cycle, and includes a plurality of current consumption units (21) for performing the current consumption operation. The number of the current consumption units performing the current consumption operation during the operation suspension period of the first circuit is made to be variable. Because the consumed current amount by the current consumption circuit is set by the number of current consumption units whose operations are selected, it is possible to easily cope with even a case where the estimation of the current amount in advance is difficult.  <P>COPYRIGHT: (C)2009,JPO&INPIT
