AXI Background • Advanced eXtensible Interface (AXI) is a communication interface that is • parallel • high-performance • synchronous • high-frequency • multi-master and multi-slave • AXI targets on-chip communication in System-on-Chip (SoC) designs • AXI is available royalty-free and its specification is freely available from ARM
The AXI protocol has several key features that are designed to improve bandwidth and latency of data transfers and transactions, as you can see here: Independent read and write channels: AXI supports two different sets of channels, one for write operations, and one for read operations.
The Advanced Microcontroller Bus Architecture, or AMBA, is an open-standard, on-chip interconnect specification for the connection and management of functional blocks in system-on-a-chip (SoC) designs. Essentially, AMBA protocols define how functional blocks communicate with each other.
•Describe the transaction channels read and write operations for the AMBA AXI protocol. •Explain the channel timing mechanism for AXI, including the clock, reset, and VALID and READY handshake mechanism.
Xilinx® adopted the Advanced eXtensible Interface (AXI) protocol for Intellectual Property (IP) cores beginning with the Spartan®-6 and Virtex®-6 devices. Xilinx has continued the use of the AXI protocol for IP targeting the 7 series, and the Zynq™-7000 Extensible Processing Platform (EPP) devices (Zynq is in Beta development.)
AXI Master / AXI Slave. Transaction: Transfer of data from one point in the hardware to another point. Master: Initiates the transaction. Slave: Response to the initiated transaction. Write Transaction Data.
