ESP32-S3 gets SIMD-accelerated FAST feature detection
What happened
On October 26, Hacker News' front page featured work on speeding up computer vision on the roughly $2 ESP32-S3 microcontroller. The developer used the chip's 128-bit SIMD instructions to build an accelerated FAST feature detector. The report puts throughput at 11.2MP/s, up from 5.1MP/s, which it describes as about a 220% gain. Processing one QVGA (320×240) frame takes about 6 milliseconds. The reported progress covers this detector's implementation and its performance numbers.
