Flexible Architecture Design for H.265/HEVC Inverse Transform
Highly-efficient video coding involves a great amount of computations. Hardware encoders apply different parallelization techniques to satisfy real-time requirements. This paper describes a novel design methodology for the 2D inverse transform used in the H.265/HEVC hardware decoder and encoder. To support different transform sizes, matrix multiplications are decomposed into some steps based on...
متن کاملDecoder Hardware Architecture for HEVC
This chapter provides an overview of the design challenges faced in the implementation of hardware HEVC decoders. These challenges can be attributed to the larger and diverse coding block sizes and transform sizes, the larger interpolation filter for motion compensation, the increased number of steps in intra prediction and the introduction of a new in-loop filter. Several solutions to address ...
متن کاملDesign and Implementation of a High-Throughput CABAC Hardware Accelerator for the HEVC Decoder
HEVC is the new video coding standard of the Joint Collaborative Team on Video Coding. As in its predecessor H.264/AVC, Context-based Adaptive Binary Arithmetic Coding (CABAC) is a throughput bottleneck. This paper presents a hardware acceleration approach for transform coefficient decoding, the most time consuming part of CABAC in HEVC. In addition to a baseline design, a pipelined architectur...
متن کاملA High Performance HEVC De-Blocking Filter and SAO Architecture for UHDTV Decoder
High efficiency video coding (HEVC) is the next generation video compression standard. In-loop filter is an important component of HEVC which is composed of two parts, deblocking filter (DBF) and sample adaptive offset (SAO). In this article, we propose a high performance in-loop filter architecture for HEVC which integrate both deblocking filter and SAO. To achieve it, several ideas are adopte...
متن کاملthe algorithm for solving the inverse numerical range problem
برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
