VLIW architecture compilation-simulation and its implementation into FPGA
International audience; Embedded systems present a tremendous opportunity to customize designs by exploiting the application behavior. Shrinking time-to-market, coupled with short product lifetimes, create a critical need for rapid exploration and evaluation of candidate architectures achievement of these constraint. In the recent years, these systems have grown to the new concepts with inner computing processing for improving the performance that will be known as embedded computing system. Embedded computing with VLIW (Very Long Instruction Word) based architecture has been alternative choice to implement the target application into electronics devices in many areas such as digital image p…
Concept and Development of Modular VLIW Processor Based on FPGA
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance VLIW processor core in an FPGA. Architecture based on Very Long Instruction Word (VLIW) processors are an optimal choice in the attempt to obtain high performance level in embedded system. In VLIW architecture, the effectiveness of these processors depends on the ability of compilers to provide sufficient instruction level parallelism(ILP) in program code. Using advanced compiler technology could take these functions, This paper describes research resu…
Design Space Exploration for a Custom VLIW Architecture: Direct Photo Printer Hardware Setting Using VEX Compiler
Increasingly more computing power is demanded for contemporary applications such as multimedia, 3D visualization, and telecommunication. This paper presents a design space exploration (DSE) experience for an embedded VLIW processor that allows finding out the best architecture for given application. The proposed method has been implemented and tested using an image processing chain for direct photo printer. Our results show a considerable improvement in hardware cost and performance. After the best architecture is identified, we applied a technique to optimize the code in VEX system that uses ?inlining? function in order to reduce execution time.
Conception d'un outil de prototypage rapide sur le FPGA pour des applications de traitement d'images
This manuscript presents work to propose a development cycle to establish RISP processors in a reprogrammable chip (FPGA). After a description of the various possible solutions to produce image processing prototypes, this document describes a method which consists in generating hardware models of processor target to image processing, with operators just for a given application. Test with a set of common algorithm makes evaluate the performances of the design cycle proposed. Rapid prototyping of a contact less biometric system, based on palmprint recognition, is also realized on the test platform.
Flexible VLIW processor based on FPGA for real-time image processing
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance Very Long Instruction Word (VLIW) processor core in an FPGA. With VLIW architecture, the processor effectiveness depends on the ability of compilers to provide sufficient Instruction Level Parallelism (ILP) from program code. This paper describes research result about enabling the VLIW processor model for real-time processing applications by exploiting FPGA technology. Our goals are to keep the flexibility of processors in order to shorten the developm…
