SNR-Aware Error Detection for Low-Power Discrete Wavelet Lifting Transform in JPEG 2000
Found in: Defect and Fault-Tolerance in VLSI Systems, IEEE International Symposium on
By Shih-Hsin Hu, Tung-Yeh Wu, Jacob A. Abraham
Issue Date:October 2009
pp. 136-144
This paper presents a SNR-aware error detection technique for a low-power wavelet lifting transform architecture in JPEG 2000. Power reduction is done by over-scaling the supply voltage (voltage-over-scaling (VOS)). A low-cost SNR-aware detection logic is ...
Error detection in 2-D Discrete Wavelet lifting transforms
Found in: On-Line Testing Symposium, IEEE International
