the transformation of 2D-DCT is applied in video compression technique with 14 additions for area and power compaction. The proposed structure could be implemented in 4, 8, 16, 32 bit size. The proposed 2D-DCT system is used to reduce the complexity of video compression. It results in less area delay and power consumption with “0” and “1” by implementing in FPGA. HEVC/H265 is applied for enhanc...

This paper presents a methodology for the automatic definition of NoC topology according to application and architecture requirements. The proposed solution, which has been implemented as a new step of our NoC design flow, results from the analysis of real concerns and demands from designers. The main contribution lies in the fact that we customize the method according to multiprocessor archite...

The H.264/AVC standard defines an optional in-loop deblocking filter. The effect of this filter on subjective video quality is investigated. Filter settings preferred by users are recorded for a group of 82 users across a range of video sequences and coded bitrates. The results indicate two clear groupings of user preferences for lowand medium-activity sequences. There is no clear user preferen...

This paper presents new constructions of families of binary and ternary arrays with low off-peak (periodic) autocorrelation and low cross-correlation for application to video watermarking. The constructions are based on the composition method which uses a shift sequence to cyclically shift a commensurate “column” sequence/array. The shift sequence/array has auto and cross-hit values constrained...

Hardware/software co-simulation improves the performance of embedded applications by executing the applications on a virtual platform before the actual hardware is available in silicon. However, the virtual platform of the target architecture is often not available during early stages of the embedded design flow. Consequently, analysis for parallel execution without performing hardware/software...

Astex, Automatic Speculative Thread EXtractor, is a compiler front-end we devellop for automatic C-code partitioning in speculative codelets, i.e. pure function that can be distributed over computing units of a system. It is an hybrid approach mixing static analysis and speculative data from profiles to offline generating a partition of the input C sequential code. In addition to the generated ...
