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.
Rapid Digital System Prototyping: Current Practice, Future Challenges
A top-down methodology that emphasizes modular, upgradable designs solves some problems with the current design process for application-specific signal processors. Virtual prototyping, model year architectures, and reuse-based design form the pillars of this new approach, which promises to raise industrial design productivity and competitiveness.
Fast seismic data compression based on high-efficiency SPIHT
Based on the set positioning in hierarchical tree (SPIHT) algorithm, fast seismic data compression based on the high-efficiency SPIHT (HESPIHT) algorithm is presented. To verify the validity of the algorithm, 10 seismic cross-sections are selected for the experiment. The result shows that the algorithm can reserve the quality of data better, meanwhile improving the efficiency of encoding and decoding.
