Hardware-accelerated Implementation of EMD Hardware and Software Co-design Evalution for HHT

چکیده
Hilbert Huang Transform (HHT) is an empirical timefrequency analysis method firstly proposed by N. E. Huang in 1998. This method is suitable for nonlinear and non-stationary signal processing and thus employed for bioelectrical signal processing and analysis in recent years. However, the large computation cost of HHT restricts its applications for real-time signal processing. This paper presents a hardware accelerated HHT system based on Field Programmable Gate Array (FPGA), which employs hardware and software co-design techniques to effectively improve the processing speed.

متن کاملOn Feasibility of Adaptive Level Hardware Evolution for Emergent Fault Tolerant Communication
A permanent physical fault in communication lines usually leads to a failure. The feasibility of evolution of a self organized communication is studied in this paper to defeat this problem. In this case a communication protocol may emerge between blocks and also can adapt itself to environmental changes like physical faults and defects. In spite of faults, blocks may continue to function since ...
