Journal ArticleDOI
Power-Efficient Sum of Absolute Differences Hardware Architecture Using Adder Compressors for Integer Motion Estimation Design
Bianca Silveira,Guilherme Paim,Brunno Abreu,Mateus Grellert,Claudio Machado Diniz,Eduardo Costa,Sergio Bampi +6 more
TL;DR: In this paper, the authors exploit different adder compressors structures into the SAD hardware architecture and synthesize an 8-2 compressor with 4-2 compressors and Kogge-Stone adder in the recombination line.
Journal ArticleDOI
A Cross-Layer Gate-Level-to-Application Co-Simulation for Design Space Exploration of Approximate Circuits in HEVC Video Encoders
TL;DR: The approach shows that the lower-part-or and error-tolerant adder I approximate adders, as well as truncation-to-zero deliver better compression-power trade-offs, with substantial differences from the static analysis.
Journal ArticleDOI
Approximate Pruned and Truncated Haar Discrete Wavelet Transform VLSI Hardware for Energy-Efficient ECG Signal Processing
Henrique Seidel,Morgana M. A. da Rosa,Guilherme Paim,Eduardo Costa,Sergio Almeida,Sergio Bampi +5 more
TL;DR: In this paper, an approximate Haar discrete wavelet transform (HDWT) hardware architecture for ECG processing at very high energy efficiency is presented. But, the authors do not consider the use of a truncation technique to improve energy efficiency.
Journal ArticleDOI
Power-, Area-, and Compression-Efficient Eight-Point Approximate 2-D Discrete Tchebichef Transform Hardware Design Combining Truncation Pruning and Efficient Transposition Buffers
Guilherme Paim,Leandro M. G. Rocha,Gustavo M. Santana,Leonardo Bandeira Soares,Eduardo Costa,Sergio Bampi +5 more
TL;DR: This work proposes a new approximation for the 8-point DTT, with a higher power- and compression-efficiency by exploring coefficient truncation, leading to the values 1/16, −1/ 16, 1/8, and −1/, and achieves higher compression ratio and less quality loss in the compressed image.
Journal ArticleDOI
On the Resiliency of NCFET Circuits Against Voltage Over-Scaling
Guilherme Paim,Georgios Zervakis,Girish Pahwa,Yogesh Singh Chauhan,Eduardo Costa,Sergio Bampi,Jorg Henkel,Hussam Amrouch +7 more
TL;DR: In this paper, the authors investigated the resiliency of negative capacitance transistor (NCFET) technology to VOS in comparison to conventional CMOS technology and showed that the VOS-resilience of NCFET circuits enables maximizing the voltage decrease.
