Using a specific input-restructuring sequence, a new VLSI algorithm and architecture have
been derived for a high throughput memory-based systolic array VLSI implementation of a …

This paper introduced a matrix parametrization method based on the Loeffler discrete cosine
transform (DCT) algorithm. As a result, a new class of 8-point DCT approximations was …

A computational complexity control algorithm is proposed for an H. 264 encoder running on
a processor/power constrained platform. This new computational complexity control …

This work presents an efficient low-complexity method to compute a 2-D inverse transform
flexibly adapted to its end-of-block (EOB) point and corner coefficients. First, the EOB point is …

Cette thèse est élaborée en cotutelle entre l'université Badji Mokhtar (Laboratoire LERICA)
et l'université de bourgogne (Laboratoire LE2I, UMR CNRS 5158). Elle constitue une …

In this paper a fast processing architecture for the transform and quantization of the H.
264/AVC, named DQ engine, is proposed. Compare with the traditional architecture …

The Discrete Cosine Transform (DCT) plays an important role in various DSP applications
as it is a good alternative to Discrete Fourier Transform (DFT). In this paper, we have …

Many-core processor architecture has become the most promising computer architecture.
However, how to utilize the extra system performance for real applications such as video …

Using a new VLSI algorithm for 1-D DCT a new VLSI architecture has been obtained that
can be unified with that for 1-D DST. The proposed architecture has some appealing …
