网页The AXIM interface is a single 64-bit wide interface that connects to an external memory system. It is used for: Instruction fetches. Data cache linefills and evictions. Non-cacheable Normal-type memory data accesses. Device and Strongly-ordered type data accesses, normally to peripherals.
网页STM32F7 microcontrollers integrate an AXI-to-Multi-AHB bridge to take advantage of the Cortex®-M7 AXIM interface. The AXI de-correlates the access request from the data phase, so the request is independent from its corresponding data. If the memory has latencies, this separation makes the bus available to perform a new
