Concept and Development of Modular VLIW Processor Based on FPGA
2010
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…
Multiple modular very long instruction word processors based on field programmable gate arrays
2007
Modern field programmable gate array (FPGA) chips, with their large 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. This paper describes research results about enabling the DSP TMS320 C6201 model for real-time image processing applications by exploiting FPGA technology. We present a modular DSP C6201 VHDL model with a variable instruction set. We call this new development a minimum mandatory modules (M3) approach. Our goals are to keep the flexibility of DSP in order to shor…
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.

Design Space Exploration for a Custom VLIW Architecture: Direct Photo Printer Hardware Setting Using VEX Compiler
2008
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.
Optimizing the Integration Area and Performance of VLIW Architectures by Hardware/Software Co-design
2021
The cost and the performance are major concerns that the designers of embedded processors shall take into account, especially for market considerations. In order to reduce the cost, embedded systems rely on simple hardware architectures like VLIW (Very Long Instruction Word) processors and they look for compiler support. This paper aims at developing a design space explorer of VLIW architectures from different perspectives like processing performance and integration area. A multi-objective Genetic Algorithm (GA) was used to find the optimum hardware configuration of an embedded system and the optimization rules applied by compiler on the benchmarks code. The first step consisted in represen…
