Color Space Conversion for MPEG decoding on FPGA-augmented TriMedia Processor

A case study on Color Space Conversion (CSC) for MPEG decoding, carried out on FPGAaugmented TriMedia processor is presented. That is, a transform from Y0CbCr color space to R0G0B0 color space is addressed. First, we outline the extension of TriMedia architecture consisting of FPGA-based Reconfigurable Functional Units (RFU) and associated instructions. Then we analyse a CSC (RFU–specific) inst...

Performance Evaluation of Interleaved Multithreading in a VLIW Architecture

Interleaved multithreading is a technique in which the processor starts executing a different task when the current thread is stalled. However, whereas different forms of hardware multithreading have been extensively evaluated in superscalar processors, an evaluation of multithreading techniques in a VLIW architecture is frequently missing. The objective of this paper is to determine an efficie...

-to-RGB Color Space Conversion on FPGA-augmented TriMedia-32 Processor

This paper investigates Y UV -to-RGB color space conversion on FPGA-augmented TriMedia-32 processor. First, we outline the extension of TriMedia-32 architecture consisting of FPGA-based Reconfigurable Functional Units (RFU) and associated generic instructions. Then we analyse a YUV-RGB (RFU–specific) instruction which can process four pixels per call, and propose a scheme to implement the YUV-R...

MPEG Macroblock Parsing and Pel Reconstruction On An FPGA-Augmented TriMedia Processor

This paper describes an experiment which aims to reveal the potential impact on performance yielded by augmenting a TriMedia-CPU64 processor with a multiple-context FPGA core. We first propose an extension of the TriMediaCPU64 architecture, which consists of a Reconfigurable Functional Unit and its associated instructions. Then, we address the decoding of variable-length codes on such extended ...

Optimisation of Multimedia Applications for the Philips Wasabi Multiprocessor System

Libavcodec is an open source software library that contains many different audio/video codecs. In this work, it is optimised and parallelised for the Philips Wasabi chip multiprocessor, which is currently being developed at Philips. Wasabi contains several DSPs and one or more general-purpose processors. The TriMedia-style optimisations (in particular utilising the SIMD custom operations) impro...
