This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example whb bursts. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. You copied the Doc URL to your clipboard. It is supported by ARM Limited with wide cross-industry participation.

An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect. Was this page helpful? By disabling cookies, some features of the site will not work. This subset simplifies the design for a bus with a single master.

Important Information for the Arm website. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. The timing aspects and the voltage levels on the bus are not dictated by the specifications. Computer buses System on a chip. AXIthe third generation of AMBA interface defined in the AMBA 3 specification, is targeted at high performance, high clock frequency system designs and includes features that make it suitable for high speed sub-micrometer interconnect:.
