title: 8 bit shifter -VHDL
body: <p>I am trying to use xilinx tools to define and simulate an 8-bit shifter in VHDL that can shift or rotate left or right by 0,1,2 or 3 bit positions. I'm trying to implement this on a digilent basys 2 board.</p>
  
  <p>I am just beginning to learn vhdl programming. Can anyone please help?
  Can anyone show me what the vhdl code should look like?</p>
