Abstract
An object of the present invention is to provide a semiconductor device that can prevent performance degradation due to wasted execution cycles. According to the present invention, a fetch is performed in an information fetch block (IFB) on the basis of the status of a branch-taken signal (BRTKN) provided from an execution block (EXB), wherein if a conditional branch is taken, the IFBselects a branch target address and if not, the IFBselects an address of the next instruction. The IFBthen provides the selected address to an instruction memory () to control the fetch in accordance with the address.
