Object-oriented programming of DSP processors: a case study of QuickC30

Object-oriented programming (OOP) is a new paradigm and methodology for software development and design. A case study of applying OOP to the programming of the TMS320C30 signal processors in time-critical applications is presented. Data types and structures are defined as classes (abstract data types) in a systematic way without need for compromising between flexibility and efficiency. Procedurally the environment supports method (function) definitions in a high-level language, low-level macro instructions, and middle-level method instruction definitions integrated by a common syntax so that even low-level instructions may refer to the high-level OOP data types. The system is implemented in Common Lisp and follows the syntax of Common LISP Object System (CLOS). Several examples of digital signal processor (DSP) programming are given
