MG200 – NS32332 Legacy In June 2015, Udo Möller released a complete Verilog implementation of an NS32000 processor on OpenCores. Fully software-compatible with an NS32532 CPU with N32381 FPU, it is significantly faster when implemented on an FPGA, both operating at a higher clock rate and using fewer cycles per instruction.
