Image Super-Resolution and Multiple Video Playback on TV sets using Cell Processor

This paper describes new AV Applications for TV sets using Cell Processor. The Image Super-Resolution converts standard definition to vivid high definition image better than conventional up-scaler. The Multiple Video Playback decodes and displays 48 video streams on the screen with optimized program.

Digital media applications on a CELL software platform

The heterogeneous multi-core architecture of the CELL processor requires a software layer in order to effectively run application programs on a CELL platform. We have developed an application framework which enables programmers to exploit this software layer and develop digital media applications easily. Using this application framework, we have developed a real-time digital media application that includes functions such as a receiver for digital television broadcasting. As software components for this digital media application, we have also developed a real-time H.264 software decoder and encoder. Although it is said that an H.264 software decoder or encoder requires a large amount of computation power, the CELL platform is able to execute it effectively and satisfy the real-time requirements for digital media applications.

Parallelization strategy for CELL TV

Consumer electronics devices are moving forward to utilize multi-core processors. We have developed a series of unique applications for TV based on Cell Broadband EngineTM (Cell/B.E.). This paper introduces such applications realized by the capability of the multi-core processor, and shares the strategy we took to exploit its potential.

Implementation of total variation regularization algorithm on CELL processor

The total variation (TV) regularization method is very effective and attractive for various image processing applications. The problem with the TV approach is the long computational time resulting from iterative calculations, which has been considered to be a major hurdle for its application to motion pictures. In this study, we have implemented the TV algorithm on the CELL processor by using various special programming techniques and an optimum software design.

Full GPGPU implementation of 2D-3D conversion on laptop GPU

This paper describes the General-Purpose computing on Graphics Processing Unit (GPGPU) optimized implementation of 2D-3D Conversion. 2D-3D Conversion is large-scale image processing and consists of 170 kernels. Those kernels, which are tasks performed by GPU, contain various algorithms. 30fps real-time processing of 2D-3D Conversion conventionally requires special hardware since it is computationally expensive. To clarify the feasibility of real-time processing by software, we did full GPGPU implementation of all image processing of 2D-3D Conversion on a laptop PC.
