We recommend upgrading your browser. AMBA is a solution for the blocks to interface with each other. Allows implementations to reach higher clock frequencies by making it easy to re-time without losing throughput.

The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. A split channel architecture to increase throughput by taking full advantage of deeply pipelined SDRAM memory systems. ChromeFirefoxInternet Explorer 11Safari. Performance, Area, and Power. The key features of the AXI4-Lite interfaces are: The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.

Architecture | AMBA 4 – Arm Developer

Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides. The AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization of the interconnect when used by multiple masters.

These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties.

AXIthe third generation of AMBA interface defined in the AMBA abma specification, is targeted at high performance, high clock frequency system designs and includes features that make it suitable for high speed sub-micrometer specicication. AXI4 is an update to AXI3 to enhance the performance and utilization of the interconnect when used by multiple masters.

AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. Forgot your username or password?

Q-Channel to manage autonomous hierarchical clock gating and simple component power control. Supports both memory mapped and streaming type interfaces Provides a unified interface on IP across communications, video, embedded and DSP functions Is easy to use, with features like automatic pipeline instantiation to help you more easily hit a speciication performance target Is equal to or better than current solutions in key attributes, such as fMAX, LUT usage, latency, and bandwidth.

Key features of the protocol are: ACE also adds barrier support to enforce ordering of multiple outstanding transactions, thus minimizing CPU stalls waiting for preceding transaction to complete.

This bus has an address and data phase sepcification to AHB, but a much reduced, low complexity signal list for example no bursts.

It includes the following enhancements: ACE-Lite also supports barriers.

Ready for adoption by customers Standardized: The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.

The key features of the AXI4-Lite interface are: Tailor the interconnect to meet system goals: This page was last edited on 28 Novemberat Views Read Edit View history.

Key features of the protocol are:. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.

Socrates System IP Tooling. Computer buses System on a chip. Technical and de facto standards for wired computer buses. APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. This subset simplifies the design for a bus with a single master. AXI4 is open-ended to support future needs Additional benefits: It is supported by ARM Limited with wide cross-industry participation.

Support for burst lengths up to beats Quality of Service signaling Support for multiple region interfaces AXI4-Lite AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. All transactions are burst length of one All data accesses are the same size as the width of the data bus Exclusive accesses are not supported AXI4-Stream The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.

Advanced Microcontroller Bus Architecture

Key features of the protocol are:. Interfaces are listed by their speed in the roughly ascending specificatoon, so the interface at the end of each section should be the fastest. Sorry, your browser is not supported. Supports single and multiple data streams using the same set of shared wires Supports multiple data widths within the same interconnect Ideal for implementation in FPGAs.

The key features of the AXI4-Lite interfaces are:.

All interface subsets use the same transfer protocol Fully specified:
