Error Analysis

Analyze error rates of inaccurate adder/inaccurate multiplier by comparing it with accurate adder/accurate multiplier using 1 million monte carlo random sampled unsigned numbers

Adder Error Analysis

1. Type of Error Analysis to carry out, choose one of [Adder Error Analysis, Multiplier Error Analysis]

   • Default Options:
     • Adder Error Analysis

2. Total number of bits for approximate computing module

   • Default Options:
     • 4
   • Constraints:
     • 4 <= total_bits <= 32

3. Accurate bits and Inaccurate bits selection. Move slider to adjust.

   • Default Options:
     • acc_bits = 1
     • inacc_bits = 3
   • Constraints
     • 3 <= inacc_bits <= total_bits - 1

4. Type of hardware module to analyse error, chose one of [HEAA, HOERAA, HOAANED, M-HERLOA]

   • Default Options:
     • HEAA

Multiplier Error Analysis

1. Total Multiplicand bits and Total Multiplier bits

   • Default Options:
     • 4
   • Constraints:
     • multiplicand_bits >= 3
     • multiplier_bits >=3

2. V-cut

   • Default Options:
     • 3
   • Constraints:
     • 0 <= v_cut <= multiplicand_bits + multiplier_bits - 3
