Advanced Microcontroller Bus Architecture
AXI4 is an update to AXI3 to enhance the performance and utilization of the interconnect when used by multiple masters. Allows implementations to reach higher clock frequencies by making it easy to re-time without losing throughput.
Advanced Microcontroller Bus Architecture – Wikipedia
A split channel architecture to increase throughput by taking full advantage of deeply pipelined SDRAM memory systems. ACE also adds barrier support to enforce ordering of multiple outstanding transactions, thus minimizing CPU stalls waiting for preceding transaction to complete. ACE-Lite also supports barriers. It includes the following enhancements:. The key features of the AXI4-Lite interface are:.
The AXI4-Stream protocol is designed for unidirectional data transfers from master to slave with greatly reduced signal routing.
Key features of the protocol are:.
AMBA AXI4 Interface Protocol
It includes the following enhancements: The key features of the AXI4-Lite interface are: 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 secification greatly reduced signal routing.
Key features of the protocol are: Q-Channel to manage autonomous hierarchical clock gating and simple component power control.
P-Channel to manage more complex power control features to increase power efficiency. Accept and hide this message.
