On the contrary; for every RISCV32 instruction you'd expect the same energy requirement as in a bit parallel implementation. If you take 32x longer by processing 1 bit at a time, your power (energy per time unit) could be as much as 32x lower.
- kragen 4y agoyou probably know more, but my ignorant guess is that you need about half as many gates, but about 20× as many cycles (because things that would stall for an entire instruction time in a bit-parallel implementation only stall for a single cycle), it might consume about 10× as much energy? but generally the kinds of places you'd want to use something like this, the cpu won't be even 1% of the power draw
