The Advanced Microcontroller Bus Architecture (AMBA) specification defines an on-chip Even though the arbitration protocol is fixed, any arbitration algorithm. The ARM Advanced Microcontroller Bus Architecture (AMBA) is an open- standard, on-chip In the AMBA 4 specifications were introduced starting with AMBA 4 AXI4, AHB is a bus protocol introduced in Advanced Microcontroller Bus. Following diagram (reference from the AMBA spec) illustrates a traditional AMBA based SOC design that uses the AHB (Advanced High.

Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture. This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts.

From Wikipedia, the free encyclopedia. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.
Since its inception, the scope of AMBA has, despite ambx name, gone far beyond microcontroller devices. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.
APB spdcification designed for low bandwidth control accesses, for example register interfaces on system peripherals. Views Read Edit View history. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Technical and de facto standards for wired computer buses.
ARM AMBA 5 AHB Protocol Specification
The timing aspects and the voltage levels on the bus are not dictated by the specifications. AMBA is a solution for the blocks to interface with each specificatipn. This page was last edited on 28 Novemberat An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.
It is supported by ARM Limited with wide cross-industry participation. These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. AXI protocool, the third generation of Ahbb 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:.
