摘　　要：New reconfigurable computing architectures are introduced to overcome some of the limitations of conventional microprocessors and fine-grained reconfigurable devices （e.g., FPGAs）. One of the new promising architectures axe Configurable System-on-Chip （CSoC） solutions. They were designed to offer high computational performance for real-time signal processing and for a wide range of applications exhibiting high degrees of parallelism. The programming of such systems is an inherently challenging problem due to the lack of an programming model. This paper describes a novel heterogeneous system architecture for signal processing and data streaming applications. It offers high computational performance and a high degree of flexibility and adaptability by employing a micro Task Controller （mTC） unit in conjunction with programmable and configurable hardware. The hierarchically organized architecture provides a programming model, allows an efficient mapping of applications and is shown to be easy scalable to future VLSI technologies. Several mappings of commonly used digital signal processing algorithms for future telecommunication and multimedia systems and implementation results axe given for a standard-cell ASIC design realization in 0.18 micron 6-layer UMC CMOS technology.New reconfigurable computing architectures are introduced to overcome some of the limitations of conventional microprocessors and fine-grained reconfigurable devices （e.g., FPGAs）.
