The design consists of a RAM and an approximate multiplier a * b = r based on DRUM: A Dynamic Range Unbiased Multiplier for
Approximate Applications by Hashemi et. al.
r = a * b. Write data to a and b. Then read the result/s from the RAM. The product results should differ if the frequency is increased.
Address map:
- 0 to 7 => product result
- 8 => multiplicand 1
- 9 => multiplicand 2
Nothing.
