We can design high-frequency soft-processors on FPGAs that exploit deep pipelining of DSP primitives, supported by selective data forwarding, to deliver up to 25% performance improvements across a range of benchmarks. Pipelined, in-order, scalar processors can be small and lightweight but suffer fro...
