Two different ways to code a shift register in VHDL are shown. So far I believe to have made a 1- bit register, here is my code: LIBRARY ieee. Ive implemented a shift left register with serial input and parallel output using a 'slice' to implement the shift but I cant figure out how to implement the same logic using an overloaded shift operator: sll (shift left logical) operator. Main inputs of the register include clock (clk), clear (clr), load/enable(ld) signals and an n- bit data (d). I'm having some troubles in designing a 1- bit and 3.
