There is also the option to get a single precision floating point unit (FPU) on a Cortex-M4. If your application requires floating point math, you will get this done considerably faster on a Cortex-M4 than you will on a Cortex-M3. That said, for an application that is not using the DSP or FPU capabilities o

Code Size Comparison Cortex M3: IAR ARM vs Keil µVision. Ask Question Asked 7 months ago. Active 7 months ago. Viewed 196 times 1. I am currently developing a small project for an STM32F103 microcontroller which features a Cortex-M3 CPU. Due to CMSIS standard header files it is possible to use the exact same code with IAR and Keil µVision. Because of that, I found it interesting to compare. Pulse-Width Modulation (PWM) PWM operates by creating a digital output wave of a fixed frequency while allowing varying duty cycle. This gives the microcontroller the capability to vary the amount of power delivered to a load such as a motor. The figure below shows three waveforms indicating their high (H) cycle and low (L) cycles

This course is designed for engineers developing software for platforms based around Arm® Cortex®-M Series processors with v6-M and v7-M architecture. The course includes an introduction to the Arm product range and supporting IP, the processor core, programmers' model, instruction set and debug architecture. It includes a number of worked examples and hands-on CMSIS compliant exercises to. Most 32-bit examples focus on ARM Cortex-M devices, which behave very similarly across MCU vendor portfolios. There is a lot more architectural variation on the 8-bit MCU side, so it's harder to apply apples-to-apples comparisons among 8-bit vendors. For the sake of comparison, we use the widely used, well-understood 8051 8-bit architecture.
