  • How to port TensorFlow Lite for Microcontroller applications to the Arm Cortex-M55 Processor

    The Arm Cortex-M55 processor is the first processor with Armv8.1-M architecture which includes the implementation of Arm Helium Technology, also known as M-profile Vector Extension (MVE). Helium technology enables increased levels of Machine Learning and…

  • How to use the Arm Cortex-M55 Processor with the open-source CMSIS library

    Arm recently announced the Cortex-M55 processor, the first to feature Arm Helium technology, also known as the M-Profile Vector Extensions (MVE), introduced with the Armv8.1-M architecture. The vector extensions enable increased DSP and machine learning (ML…

  • Cortex-M23 FVP hard faults when using DS-5 Debugger

    Hi,

    I'm starting to explore this technology by running the TrustZone example application in Linux using GNU ARM Toolchain. This example is provided by a CMSIS software pack containing this example called "TrustZone for ARMv8-M No RTOS" which I was…

  • Why should we call secure function in handler mode?

    Why should we call secure function in handler mode? What is the design purpose for this?  As we know, none-secure side can also call secure function in thread mode.
