    Embedded Systems Essentials with Arm: Getting Started

    Module 1
    KV4 (1): Arm Architecture and Processors
    The Arm architecture is a family of RISC-based processor architectures, well known for its power
    efficiency and used in many mobile devices. The architecture details a set of instructions that define
    how the hardware should work upon execution of certain instructions. These specifications are in
    place so that software that conforms with them can be executed on any Arm-based processor.

    Arm architecture is suited for use in an array of IoT applications and includes features that meet the
    ever-evolving demands for new functionality, integrated security features, high performance and the
    needs of new and emerging markets. For example, the Armv7-M architecture used in the Arm
    Cortex-M4 processor is designed specifically for embedded systems, and so enables simple pipeline
    design, low cycle count execution, and minimal interrupt latency, all of which improve speed,
    battery life and simplicity of operation in an embedded systems environment.

    Some companies license the Arm architecture and design their own CPU based on the licensed
    architecture, rather than using a CPU designed by Arm.

    Arm architecture also forms the basis for every Arm processor.

    Although Arm processors are widely considered an industry standard, Arm itself does not
    manufacture them. Instead, Arm designs the processor cores in its hardware libraries, licenses the
    designs to producers, and provides an ecosystem of development tools and manuals. Producers
    combine these processor designs with their own intellectual property or with other third-party
    intellectual property to create a complete product.

    Arm’s processor technology is designed and optimized with the needs and constraints of IoT devices
    in mind, and so are more energy efficient. Arm processors cover IoT applications from sensors to
    servers.

    Arm Cortex-A Processors are application processors used for feature-heavy operating systems and
    third-party applications. For example, machine learning at the edge, autonomous context-based
    decision making, or securely connecting IoT devices to the cloud.

    Arm Cortex-R Processors are embedded processors for real-time signal processing and control
    applications. They meet the need for high performance, very low latency, and low power in devices
    such as connected cars, high-end cameras, or disk drive controllers.

    Arm Cortex-M Processors are microcontroller-oriented processors. They can be application-specific,


    or suitable for system-on-chip uses. They are optimized for low energy consumption and small
    executables, requiring less physical space and silicon for a lower cost.

    This course focuses on M-series processors.

    The Arm Cortex-M0 and Cortex-M0+ are designed for applications that require minimal cost, power,
    and area. These processors are optimized for simple sensing and controlling.

    The Cortex-M3, Cortex-M4 and Cortex-M7 are designed for data-intense operations with Harvard
    architecture, dedicated fast hardware multipliers, and math packages. The Cortex-M4 and Cortex-

    and power-efficient algorithm processing of digital signal control applications.
