Pipelined array divider
Maturity simulatedTargets FPGA + ASICDifficulty MediumPriority 1
Fully pipelined unsigned restoring array divider: WIDTH subtract/select rows with a register after every REG_EVERY rows; throughput one division per cycle.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
