Abstract:
The protocols of AHB bus and APB bus in AMBA system are simply described. The AHB-to-APB bridge is implemented in RTL level based on simple algorithm, PrimeCell’s algorithm and multiple clock algorithm, and the emulation results and verification results on FPGA are given. At last, application of those algorithms in chip design is illustrated.
