Problems 1. Single-cycle vs. pipelined implementation. WebDec 21, 2012 · You will get an answer in a few cycles - 3 or 4 for SP, maybe 5 for DP - depending on how you compose the adder tree (and sometimes, where the synth tools insist on adding pipeline registers!). However that is the latency - as it is pipelined, throughput will be 1 result per clock cycle. WebMar 25, 2024 · My doctor solved it in this way: Number of cycles in the loop = 15 c.c.
