ARM introduced the Advanced Microcontroller Bus Architecture (AMBA) 4.0 and its specifications define five buses/interfaces: Advanced eXtensible Interface bus (AXI), Advanced High-performance Bus (AHB), Advanced System Bus (ASB), Advanced Peripheral Bus (APB) and Advanced Trace Bus (ATB). That means more and more existing Intellectual Property (IP) must be able to communicate with AMBA4.0 bus. This paper presents an IP core design of APB Bridge, to provide interface between AXI-Lite bus and APB bus operating at different frequencies. The maximum operating frequency of the module is 168.464MHz.
