The improved code achieves a 30% speedup in mining on AVR code, giving an improvement from 260 H/s to 340 H/s. The code was tested on Arduino Nano V3 (atmega328p), but should work on any similar device.
The performance improvement was achieved mostly by reimplementation of SHA1 algorithm for specific use case and precomputation of initial 10 hashing rounds.
