AMBA AXI3
The AMBA AXI protocol supports high-performance, high-frequency system designs.
The AXI protocol:
• is suitable for high-bandwidth and low-latency designs
• provides high-frequency operation without using complex bridges
• meets the interface requirements of a wide range of components
• is suitable for memory controllers with high initial access latency
• provides flexibility in the implementation of interconnect architectures
• is backward-compatible with existing AHB and APB interfaces.
The key features of the AXI protocol are:
• separate address/control and data phases
• support for unaligned data transfers, using byte strobes
• uses burst-based transactions with only the start address issued
• separate read and write data channels, that can provide low-cost Direct Memory Access (DMA)
• support for issuing multiple outstanding addresses
• support for out-of-order transaction completion
• permits easy addition of register stages to provide timing closure.
The AXI protocol includes the optional extensions that cover signaling for low-power operation.
The AXI protocol includes the AXI4-Lite specification, a subset of AXI4 for communication with simpler control
register style interfaces within components. See Chapter B1 AMBA AXI4-Lite.
