AHB can be used in high clock frequency system modules. Here, we'll quickly go through the different signals. Port declarations, each and every signals are parameterized. AMBA AHB transfer can start with the bus master,by asserting a request signal to the arbiter. See the complete profile on LinkedIn and discover Ranjan’s connections and jobs at similar companies.
