`A`,`B`and`F`, discover that they are all 8, and so will do 8-bit arithmetic. (So, it is highly likely that the result of`(A * B)`will be truncated, because the result of the multiplication will be truncated to 8 bits before the right shift. Which is clearly nonsense, because...

If you use the add-shift multiplier from MP1, or a similarly "simple" to implement multiplier, you will not recieve full credit for the M extension and will only get [3] points. Implementing a more advanced multiplier (like a Wallace Tree) will earn [5] points. The final determination ...
the 11-Bit registers were set up to shift in the values as they were being inputted. This made this module an essential part of our PS/2 driver design. The inputs into this module were Clk, Reset, Shift_in, Load, Shift_En, and D. The outputs from this module were Shift_Out and ...
