Cortex-M4 is a high-performance embedded processor developed to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities.

The ARM Cortex-M family are ARM microprocessor cores that are designed for use in microcontrollers, ASICs, ASSPs, FPGAs, and SoCs.

The Cortex-M4F processor implements single precision floating-point data processing as defined by the FPv4-SP architecture, that is part of the ARMv7-M architecture.

The Cortex-M processor family is optimized for cost and energy-eficient microcontrollers. These processors are found in a variety of applications, including IoT, industrial and everyday consumer devices.

The Cortex-M4F adds a feature called lazy stacking. This feature avoids an increase of interrupt latency by skipping the stacking of floating-point registers, if not required, that is:

The Cortex-M4 processor features a low gate count processor core, with low latency interrupt processing that has: A subset of the Thumb instruction set, defined in the Armv7-M architecture

The 32-bit Arm® Cortex®-M4 processor core is the first core of the Cortex-M line up to feature dedicated Digital Signal Processing (DSP) IP blocks, including an optional Floating-Point Unit (FPU).

The Arm Cortex-M4 processor is an efficient 32-bit control processor with signal processing capability.

Oct 5, 2023 · The Cortex-M4F and Cortex-M4 are both 32-bit ARM processor cores targeted at embedded and IoT applications. While very similar, there are some key differences between the two that designers should consider when selecting a microcontroller.

Our TM4C12x family of 32-bit Arm® Cortex®-M4F microcontrollers (MCUs) provides a broad and scalable portfolio of highly connected devices, with integrated peripherals such as Controller Area Network, USB and Ethernet.
