Digital technologies have sparked a new dynamic on the consumer market by promoting the emergence of a plethora of innovative new applications that combine communication and multimedia processing capabilities on a single chip. As a result, the number of transistors on a single chip (currently tens of millions) and the size of embedded software (hundreds of thousands of lines) have continued to grow. One of the main challenges System-on-Chip (SoC) developers must face is how to reach the best possible compromise between the hardware/software partitioning of the different functions of the circuit in order to optimize product cost, performance, and flexibility while working within real-time limitations.
Hardware- and software-based solutions traditionally present a number of problems--most notably slower execution speeds for software and a lack of flexibility for hardware. In order to overcome these problems and speed up the hybrid-system development cycle, this project aims to combine in a new way two wellknown fields: - Multiprocessor systems - Reconfigurable processors The project will also take in to account constraints such as cost, energy-consumption, performance, and time-to-market. More specifically, the purpose of the project is to develop a set of tools (debugging system, software on processor distribution, detection of hardware extensions, etc.) and an associated platform to facilitate the implementation of multimedia algorithms and the generation of optimized code over a multiprocessor network of reconfigurable processors.
