We are evaluating the CM33. 

The CM33 documentation mentions " Integer divide unit with support for operand-dependent early termination", what does it mean by "operand-dependent early termination"?  Thanks!

Hi,

On Cortex M33 , i am trying to check software interrupt functionality. Below is the CMSIS APIs i used.  Note that the CPU is in secure world and secure VTOR is being configured.

Also, ITNS config for this line is set to secure.

I am doing a survey of the Cortex-M processors, and came across the M23/M33, which are described as having very low power like the M0. Are there some actual numbers (for example, with the smallest configuration, with TrustZone, in 28HPM or 40LP)? Or,…

Hi,

I am trying to build software(esp device driver support) for a particular Cortex-M33 microcontroller offering from my company. I have a few questions about software IDE and tools supported by ARM:

• Does Keil MDK (uVision) version 5.26.2 support building…

This question was raised in the 'How to implement a secure IoT system on ARMv8-M' webinar, view all the questions in the round up blog post.

As a product manager for the Cortex-M33, I see this question pop up a lot. Below is my version of the answer.

Characteristics of TrustZone technology

• TrustZone is the security foundation for billions of ARM Cortex-A processor-based systems
• TrustZone…

Another question that I see come up once in a while.

Both the Cortex-M33 and the Cortex-M23 support TrustZone for ARMv8-M.

Cortex-M23 is the smallest lowest power TrustZone Cortex processor from ARM.

Cortex-M33 is a general purpose TrustZone processor…

Both processors have TrustZone for ARMv8-M. The following table compares the other top level features.

This is a very common question.

Hello,

I am using Cortex-M33 FVP model to run the Keil RTX TrustZoneV8M RTOS example.
Have also tried to experiment with the memory map configuration and the corresponding SAU region programming for NS/S patitioning and the behaviour is as expected.

However…

Such as the title, I have a board of MPS3

I want to try to use the microphone to input the sound, then output through the speaker.

But I have been unable to find a way. I hope someone can point me out. Thank you.
