@dougmerritt@mathstodon.xyz I have yet to meet a person who’s no fan of 7400, and I doubt such a person exists.😀 Talk about cycles: the Cortex-M has 12-cycle ISR response time. For something that low-end, that is admirable, I thought. Even in embedded arena, few uses assembly anymore, these days. Given the complexity of the pipeline, vector processor, the lot, I suppose few could out optimise a good compiler. I know I can’t.
