AMBA is a solution for the blocks to interface with each other.

It is supported by ARM Limited with wide cross-industry participation. Easy addition of register stages to achieve timing closure Architecture A split channel architecture to increase throughput spcification taking full advantage of deeply pipelined SDRAM memory systems. Technical and de facto standards for wired computer buses. Enables you to build the most compelling products for your target markets. The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.

AXI4 is an update to Speciffication to enhance the performance and utilization of the interconnect when used by multiple masters. The key features of the AXI4-Lite interface are: AXI4-Lite is a subset of the AXI4 protocol intended for communication with simpler, smaller control register-style interfaces in components. We recommend upgrading your browser.

Advanced Microcontroller Bus Architecture

Please upgrade to a Xilinx. Includes standard models and checkers for designers to use Interface-decoupled: These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. It includes the following enhancements: A split channel architecture to increase throughput by taking full advantage of deeply pipelined SDRAM memory systems. The timing aspects and the voltage levels on the bus are not dictated by the specifications.

Tailor the interconnect to meet system goals: This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. 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.

This subset simplifies the design for a bus with a single master. Views Read Edit View history. Key features of the protocol are: P-Channel to manage more complex power control features to increase power efficiency. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. JavaScript seems to be disabled in your browser. 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.

Important Information for the Arm website. 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 specific performance target Is equal to or better than current solutions in key attributes, such as fMAX, LUT usage, latency, and bandwidth.

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. Performance, Area, and Power. 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:.
