The Designer's Guide to the Cortex-M Family is a tutorial-based book giving the key concepts required to develop programs in C with a Cortex M-based processor. The book begins with an overview of the Cortex-M family, giving architectural descriptions supported with practical examples, enabling the engineer to easily develop basic C programs to run on the Cortex-M0/M3 and M4. It then examines the more advanced features of the Cortex architecture, such as memory protection, operating modes and dual stack. Those used to 8- and 16-bit architectures will find advice on how to do RTOS development. This book offers embedded systems engineers and students detailed coverage of: the key differences between the Cortex M0/M3 and M4; the key features of the Cortex-M family; how to make best use of the CoreSight debug system; the Cortex-M operating modes and memory protection; advanced software techniques for Cortex-M microcontrollers; introduces the Cortex microcontroller software interface standard (CMSIS), a common framework for all Cortex M- based microcontrollers; introduction to the CMSIS DSP library for Cortex M3 and M4, discusses how to optimize DSP code for the Cortex M4, and how to build real-time DSP systems; and an evaluation tool chain IDE and debugger allows the accompanying example projects to be run in simulation on the PC or on low-cost hardware.
