IP re-use requires a common standard while supporting a wide variety of SoCs with different power, performance and area requirements. With its ACE, AXI, AHB and APB interface protocols, AMBA 4 has the flexibility to match every requirement. With the AMBA 5 CHI interface ARM extends performance and scalability to many coherent processors.
It is a standard interface specification that ensures compatibility between IP components from different design teams or vendors. The AMBA specifications are available as both a written specification as well as a set of assertions that unambiguously define the interface protocol, thus ensuring this level of compatibility.
There is a large amount of IP available in the industry today. AMBA facilitates this IP and engineers across the globe have accepted it as a standard and use it daily. It is the most widely adopted industry standard for on-chip connectivity for IP products such as Memory Controllers, Interconnects, Trace solutions, GPUs, CPUs.
The wide adoption of AMBA specifications throughout the semiconductor industry has driven a comprehensive market in third party IP products and tools to support the development of AMBA-based systems. The availability of SystemVerilog assertions for AMBA promotes this industry-wide participation.
