Hello to all,
Since I am working on ARM Cortex-M4, I would like to know about the handling of the hazard situations (especially the RAW, WAR and WAW hazard situations) in the pipeline.
Is the processor also use the method of "Forwarding" in order to handle…
Hi
Now I'm trying to understand about memories in the Cortex design kit.
I came across memory address map of cortex M3 when I googling as the below.
In the image, left one is an AHB memory map, and right one is STM32F103's memory map.
As you…
AMBA spec states that 'Master can choose whether to terminate current burst or continue with burst in response to ERROR'.What does Cortex-M3/M4 do in response to ERROR? Does it continue with burst in response to ERROR in some special cases?
This is a very common question.
The diagram below is a pictorial description of the differences followed by some explanations.

This is a very common question too.

Wenkwei asked: "with the M3 designstart CMSDK, is it possible to design multi-master bus? In the IoT Cortex-M TRM, only an ahb-lite structure is illustrated. That document does mention AHB and APB expansion through INTEXP[1:0] but what if there are more…
