Is there perfomance gain for plain ESP32? #1

Very exciting development! I see benchmark numbers comparing ANSI C vs Assembly optimized for ESP32-S3. Have you tried comparison benchmarks for ESP-NN ANSI C vs vanilla tflite-micro ops? Is there any performance gain in that case for ESP32 (plain, not S3 version)?

Hi @AIWintermuteAI

Thanks for the interest! The gain is about 2x when ANSI C versions of ESP-NN are compared with tflite-ops with no changes. This flag when commented out, uses vanilla tflite-micro kernels. When enabled, it uses ANSI C versions OR assembly optimized ESP32-S3.

Thanks for lightning speed reply! Excited to use ESP-NN then. I'll close the issue.
