*** UNDER CONSTRUCTION ***
Benchmarking is a useful tool in testing how fast a processor can run. With the PIC32, we are primarily interested in seeing how fast its CPU can perform mathematical operations.
Overview
Details
The common arithmetic operators, multiplication (*), division(/), addition (+), and subtraction (-) were tested on the PIC32. Because timing results can vary depending on which C data type (char, short, int, long long, float, and double) is used, the final table includes the number of cycles a particular operator and data type pair took to compute.
| char | short | int | long long | float | double | |
| add (+) | 5 | 5 | 5 | 12 | 68 | 101 |
| sub (-) | 5 | 5 | 10 | 79 | 125 |
A small subset of the built-in mathematical functions defined in <math.h> were also tested.
