<p><P>PROBLEM TO BE SOLVED: To provide a semiconductor device which prevents malfunction resulting from clock skews while preventing the scale of the device from increasing and the efficiency of transfer from deteriorating. <P>SOLUTION: The semiconductor device comprises a plurality of function blocks 2, 3; an interface part 4; a clock generation part 11; and clock delay adjustment parts 12, 13 for the respective function blocks 2, 3. The clock delay adjustment parts 12, 13 switch the delay of clocks based on first and second delay adjustment control signals 60, 70 coming respectively from the first and second function blocks 2, 3. The interface part 4 switches an interface protocol between a synchronous interface and an asynchronous interface according to a synchronization request signal 50 coming from the first function block 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
