This video provides examples of creating APB completers on the Tang Nano 4K FPGA development board. The completers are modules that use the ARM APB2 protocol and implement memory-mapped registers that software on the FPGA's Cortex M3 can read and write. One completer does nothing but implement 4 registers; a second implements a simple PWM controller. Both completers are in Verilog and provide a template for integrating your own designs on the FPGA that interact with software on the M3.
