Design and implementation of APB bridge based on AMBA 4.0
Chenghai Ma, Zhijun Liu, Xiaoyue Ma · 2011
ARM introduced the Advanced Michocontroller Bus Architecture (AMBA) 4.0 specifications in March 2010, which includes Advanced eXtensiable Interface (AXI) 4.0. AMBA bus protocol has become the de facto standard SoC bus. That means more and more existing IPs must be able to communicate with AMBA 4.0 bus. Based on AMBA 4.0 bus, we designed an Intellectual Property (IP) core of Advanced Peripheral Bus (APB) bridge, which translates the AXI4.0-lite transactions into APB 4.0 transactions. The bridge provides an interfaces between the high-performance AXI bus and low-power APB domain.
