<P>PROBLEM TO BE SOLVED: To generate data after an optional phase shift in a short period of time in an M sequence generation circuit using a feedback shift register. <P>SOLUTION: A one shift circuit 220 calculates data after one shift in an internal state of an m stage flipflop 260, and an n shift circuit 230 calculates data after n shift (n≥2) in an internal state of the m stage flipflop 260. The m stage flipflop 260 sequentially holds outputs of the one shift circuit 220 or the n shift circuit 230 after setting an initial value, outputs an internal state corresponding to a shifted M sequence to a latching circuit 270 to make the latching circuit 270 output the external state as an m-bit bus signal. In addition, the internal state is feedbacked to the one shift circuit 220 and the n shift circuit 230. <P>COPYRIGHT: (C)2004,JPO |
