The goal is to produce a low-energy hardware classifier for embedded applications doing local processing of sensor data.

One efficient way of doing that in analog hardware is the use of current-starved inverters.

Since “peak performance” for the processor is two (512-bit SIMD) FMA instructions per cycle, any instructions that are not FMA instructions subtract directly from the available peak performance. Timers and hardware performance counters are measured immediately outside the loop, where their overhead is negligible.
