Design of a Reconfigurable Multiprocessor Core for Higher Performance and Reliability of Embedded Systems

In this paper design of multiprocessor core for embedded systems is discussed. The advantage of computational performance of FPGA based reconfigurable systems for embedded system is combined with fault tolerance capability of reconfigurable system. A general purpose processor is attached with reconfigurable co-processor for enhanced performance. The unit is replicated for enhanced performance and fault tolerance. The processors are communicating through central reconfiguration unit. This unit is hardware reconfigurable and uses spare logic elements in the FPGA in case of failure. The system is scalable and illustrated here for four processors
