esp32 benchmark

esp32 s3나 esp32나 비슷하고

esp8266과 esp32 c3(risc v) 비슷하다

 

esp8266이 l106

esp32 가 lx6

esp32-s2 s3가 lx7

esp32 c 는 risc-v 인데

simd는 있으나 컴파일러에는 통합 안 되었고 deep learning 으로 가속 가능한 듯

esp32-s2/3에서는 어떻게 쓸수는 있는데 eps32 에는 simd가 없나?

arm에서는 neon 혹은 sve 라고 하는데

esp 에서는 PIE 표기한다. 명령어 확장이 맞긴 한디... 흐음...

4.1.1.2 Processor Instruction Extensions (PIE) ESP32-S3 contains a series of new extended instruction set in order to improve the operation efficiency of specific AI and DSP (Digital Signal Processing) algorithms. Feature List • 128-bit new general-purpose registers • 128-bit vector operations, e.g., complex multiplication, addition, subtraction, multiplication, shifting, comparison, etc • Data handling instructions and load/store operation instructions combined • Non-aligned 128-bit vector data • Saturation operation
