Reengineering Legacy Embedded Systems
Systems that require reengineering are a fact of life in both the commercial and military arenas. The authors have developed a systematic methodology based on virtual prototyping, with accompanying tools and libraries, for rapidly upgrading electronic systems.
Virtual prototyping of embedded microcontroller-based DSP systems
We propose a hardware-software codesign process based on a design methodology called virtual prototyping. With this process, we integrate VHDL models of hardware components with application, control and diagnostic software to rapidly prototype complex, multiboard, embedded microcontroller-based DSP systems. In the virtual prototyping of a demonstration avionics system, in collaboration with Lockheed Sanders, Hughes, and Motorola RASSP teams, we reduced hardware-software integration and system test times from the typical industry figure of 10-24 months to less than a month. >
Architectures for rapid prototyping of embedded signal processors
The Rapid Prototyping of Application-Specific Signal Processors (RASSP) program is striving to change the way embedded signal processor design is performed, providing >4/spl times/ improvements in time-to-market, cost, and design quality. These improvements will be achieved using a methodology that stresses hardware and software reuse in conjunction with Model Year Architectures that facilitate reusability and upgradability through open interface standards. This paper describes a Model Year Architecture approach for the development of cost-effective signal processors that can be applied to a wide range of military and commercial applications.
