Languages such as C and Java foster the belief that programmers need only address problems at the highest levels of a program's operation. Yet, even modern coding requires an understanding of basic assembly methods such as those gained by learning ARM, as the hardware responsible for today’s coprocessors or for saturated math operations can be accessed only through its native instructions. Written by the director of ARM’s worldwide academic program, this volume examines code relevant to today's microcontrollers. Examples show students how to optimize routines and streamline coding, especially in the embedded space. The book provides access to a functional evaluation version of the RealView Microcontroller Development Kit from Keil.
