A sign extension unit extends a twos complement number from M to N (N > M) bits
Question:
A sign extension unit extends a two’s complement number from M to N (N > M) bits by copying the most significant bit of the input into the upper bits of the output. It receives an M-bit input A and produces an N-bit output Y. Sketch a circuit for a sign extension unit with a 4-bit input and an 8-bit output. Write the HDL for your design.
