Скачать или смотреть Tang Nano 4K Cortex M3 APB Access to FPGA-Based Designs

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.
