AMBA enables IP re-use
IP re-use is an essential component in reducing SoC development costs and timescales. AMBA specifications provide the interface standard that enables IP re-use if the following essential requirements are met:
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 AMBA 5 CHI interface ARM extends performance and scalability to many coherent processors.
The multi-layer architecture acts as a crossbar switch between masters and slaves in an AMBA 3 AXI or AHB system. The parallel links allow the bandwidth of the interconnect to support the peak bandwidth of the masters without increasing the frequency of the interconnect.
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.
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 AMBApromote this industry wide participation.
