We can exploit application-specific sparse structure and distribution of non-zero coefficients in Discrete Wavelet Transform (DWT) matrices to significantly improve the performance of 1-D DWT mapped to FPGA-based soft vector processors. We reformulate DWT computations specifically in terms of sparse matrix operations, where the transformation matrices have a repeating block with a fixed non-zero pattern,...
Cardiovascular diseases (CVD) are the prime causes of human mortality and morbidity worldwide. However, CVD can be prevented or cured, if detected early or on-time, where technology can be of significant help. Tackling the issue of comfort of patient by reducing the number of electrode, by allowing the remote home monitoring, and by allaying the need of physical presence of patient in hospital is...
Readback scrubbing is considered as an effective mechanism to correct errors in Static-RAM (SRAM)-based Field Programmable Gate Arrays (FPGAs). However, current solutions have a low error correction percentage per unit area overhead. This paper proposes two new error detection/correction mechanisms that combine frame readback scrubbing with error correction codes (ECCs) that are applied in multiple...
Standard 12-lead (S12) system and Mason-Likar 12-lead (ML12) system despite of being most acceptable systems for clinical usage are not the preferred lead systems for remote monitoring (RM) applications. Usually RM applications involve wireless transmission of signals and a 2–3 lead system is preferred for bandwidth and storage limitations and data transmission time. Generally, ECG compression techniques...
Fragmented QRS (f-QRS) has been found to have higher sensitivity and/or specificity values for several diseases including remote and acute myocardial infarction, cardiac sarcoidosis etc, compared to other conventional bio-markers viz. Q-wave, ST-elevation etc. Several of these diseases do not have a reliable bio-marker and hence, patients suffering from them have to undergo expensive and sometimes...
