The Yamaha YMF262 OPL3 FM Sound Synthesis chip was popular as a sound generator for PC games back in the 1990s. Greg Taylor has reverse engineered the device and written a SystemVerilog RTL description targeting the low-cost Digilent ZYBO Development Board, which is based on a Xilinx Zynq Z-7010 SoC. The design consumes less than half of the programmable logic, very little on-chip RAM, and only one the 80 available DSP48 slices:
