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. For those used to 8 and 16 bit architectures, advice is given on how to do RTOS development. 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 and discusses how to optimise DSP code for the cortex M4 and how to build real time DSP systems. . An evaluation tool chain IDE and debugger which allows the accompanying example projects to be run in simulation on the PC or on low cost hardware
