ESP32-S3 Benchmark

This repository is to help benchmark various math operations on the ESP32-S3 microcontroller. Currently, this is set up to multiply a million numbers in memory (thus exercising the PSRAM) using the following methods:

int8 using the Xtensa/Espressif SIMD instructions
int8 using standard C
Floating point using standard C

Timing information is collected during execution and displayed in the console in terms of raw time (microseconds) and "million multiply-accumulates per second" (MMACS).

To build and execute:

. ~/esp/esp-idf/export.sh
idf.py build flash monitor

Current timing results:
