load: Loads shift register with data[63:0] instead of shifting. ena: Chooses whether to shift. amount: Chooses which direction and how much to shift. 2'b00: shift left by 1 bit. 2'b01: shift left by 8 bits. 2'b10: shift right by 1 bit. 2'b11: shift right by 8 bits. q: ...
Verilog-1995 provides two simple shift operators: The >> token represents a bitwise shift-right operation. The << token represents a bitwise shift-left operation. Both shift operators will shift the bits in the first operand the number of times indicated by the value in the second operand. ...
