请问下面这段代码是干啥用的?
呵呵,本人是用VHDL的。
SboxEnc SboxEnc0(.iPreMap(RotWord[31:24]),
.oPostMap(SubWord[31:24]));
SboxEnc SboxEnc1(.iPreMap(RotWord[23:16]),
.oPostMap(SubWord[23:16]));
SboxEnc SboxEnc2(.iPreMap(RotWord[15:8]),
.oPostMap(SubWord[15:8]));
SboxEnc SboxEnc3(.iPreMap(RotWord[7:0]),
.oPostMap(SubWord[7:0]));
