Embedded C is not part of the C language as such. Rather, it is a C language extension that is the subject of a technical report by the ISO working group named "Extensions for the Programming Language C to Support Embedded Processors" [3]. It aims to provide portability and access to common performance-increasing features of processors used in the domain of DSP and embedded processing. The Embedded C specification for fixed-point, named address spaces, and named registers gives the programmer direct access to features in the target processor, thereby significantly improving the performance of applications. The hardware I/O extension is a portability feature of Embedded C. Its goal is to allow easy porting of device-driver code between systems. In this article, we focus on the performance-improving features of Embedded C.
