A 3-D Fast transform-based preconditioner for large-scale power grid analysis on massively parallel architectures
Daloukas, K.; Evmorfopoulos, N.; Tsompanopoulou, P.; Stamoulis, G. I. (2014)Efficient analysis of on-chip power delivery networks is one of the most challenging problems that EDA is confronted with. This paper addresses the problem of simulating general multi-layer power delivery networks with ... -
Fast Transform-based preconditioners for large-scale power grid analysis on massively parallel architectures
Daloukas, K.; Evmorfopoulos, N.; Drasidis, G.; Tsiampas, M.; Tsompanopoulou, P.; Stamoulis, G. I. (2012)Efficient analysis of massive on-chip power delivery networks is among the most challenging problems facing the EDA industry today. In this paper, we present a new preconditioned iterative method for fast DC and transient ... -
Fisheye lens distortion correction on multicore and hardware accelerator platforms
Daloukas, K.; Antonopoulos, C. D.; Bellas, N.; Chai, S. M. (2010)Wide-angle (fisheye) lenses are often used in virtual reality and computer vision applications to widen the field of view of conventional cameras. Those lenses, however, distort images. For most real-world applications the ... -
GLOpenCL: OpenCL support on hardware- and software-managed cache multicores
Daloukas, K.; Antonopoulos, C. D.; Bellas, N. (2011)OpenCL is an industry supported standard for writing programs that execute on multicore platforms as well as on accelerators, such as GPUs or the SPEs of the Cell B.E. In this paper we introduce GLOpenCL, a unified development ... -
Implementation and performance comparison of the motion compensation kernel of the AVS video decoder on FPGA, GPU and multicore processors
Owaida, M.; Bellas, N.; Antonopoulos, C. D.; Daloukas, K.; Antoniadis, C.; Krommydas, K.; Tsoumblekas, G. (2011)Next generation video standards have strict and increasing performance demands due to real-time requirements and the trend towards higher frame resolutions and bit rates. Leveraging the advantages of reconfigurable logic ... -
Implementation of a wide-angle lens distortion correction algorithm on the cell broadband engine
Daloukas, K.; Antonopoulos, C. D.; Bellas, N. (2009)Wide-angle lenses are often used in scientific or virtual reality applications to enlarge the field of view of a conventional camera. Wide-angle lens distortion correction is an image warping application which transforms ... -
Massively parallel programming models used as hardware description languages: The OpenCL case
Owaida, M.; Bellas, N.; Antonopoulos, C. D.; Daloukas, K.; Antoniadis, C. (2011)The problem of automatically generating hardware modules from high level application representations has been at the forefront of EDA research during the last few years. In this paper, we introduce a methodology to ... -
A parallel fast transform-based preconditioning approach for electrical-thermal co-simulation of power delivery networks
Daloukas, K.; Marnari, A.; Evmorfopoulos, N.; Tsompanopoulou, P.; Stamoulis, G. I. (2013)Efficient analysis of massive on-chip power delivery networks is among the most challenging problems facing the EDA industry today. Due to Joule heating effect and the temperature dependence of resistivity, temperature is ... -
Selective inversion of inductance matrix for large-scale sparse RLC simulation
Apostolopoulou, I.; Daloukas, K.; Evmorfopoulos, N.; Stamoulis, G. (2014)The inverse of the inductance matrix (reluctance matrix) is amenable to sparsification to a much greater extent than the inductance matrix itself. However, the inversion and subsequent truncation of a large dense inductance ... -
Synthesis of platform architectures from OpenCL programs
Owaida, M.; Bellas, N.; Daloukas, K.; Antonopoulos, C. D. (2011)The problem of automatically generating hardware modules from a high level representation of an application has been at the research forefront in the last few years. In this paper, we use OpenCL, an industry supported ...
