Description
Foundations of Computer System Design Lab
Design an 8-bit Wallace tree multiplier circuit using carry save addition (CSA)
based 3-to-2 reducers followed by CLA with higher-level propagate and generate
terms.
(a) Unsigned integer multiplier
(b) Signed integer multiplier
Test cases for unsigned integer multiplier:
2 pairs of operands that do not result in overflow.
1 pair of operands that results in overflow.
Test cases for signed integer multiplier:
Following pairs of operands that do not result in overflow:
1 pair of positive operands
1 pair of positive multiplicand operand and negative multiplier operand
1 pair of negative multiplicand operand and positive multiplier operand
1 pair of negative operands
Following pairs of operands that result in overflow:
1 pair of operands of the same sign
1 pair of operands of opposite signs
