It's called superscalar processing. CPUs can execute more than one instruction concurrently on each pipeline stage if there is no dependency between them. In the prefix sum, we can fetch and add the next element simultaneously with the accumulator of the previous iteration is being written back.

- dahart 5y agoThat link shows 1 fetch per cycle. “Pipelining does not reduce actual latency”. So your comment fails to explain both multiple fetch per cycle and higher than 1 instruction per cycle throughput on average, which is what we were discussing above.
