MP2: Acceleration Computation with SIMD in x86-64

Group 8

• Wesley Sy
• John Ian Sayat

Program Overview

• The main.c file handles:

  • Input collection (manual or randomized)
  • Memory allocation
  • Output printing

• The asmfunc.asm file (in x86-64 SIMD) handles:

  • Velocity conversion from km/h to m/s
  • Acceleration calculation
  • Conversion from float to int

Performance Analysis

We tested the ASM function for different values of input size Y:

• Y = 10
• Y = 100
• Y = 1000
• Y = 10000

Execution Times (averaged over 30 runs)

Input Size	Average Time (ms)
10	0.000000
100	0.000000
1000	0.000000
10000	0.000033

Performance Insights

• SIMD reduces computation time significantly due to parallelism.
• Performance gain is more evident with larger input sizes.
