Run-Time Reconfiguration of Processing Elements through Soft-Core Processor

This paper proposes a system-on-chip design to perform run-time reconfiguration using soft-core processor. The reconfigurable module consists of a set of Processing Elements (PEs) that are fully connected to each other through a crossbar network. Run-time reconfiguration is achieved by dynamically selecting the desired number of PEs based on the input data set through soft-core processor. This dynamic selection of PEs leads to optimum resource utilization and lesser power consumption for computationally intensive applications such as media processing. Optimization was achieved through minimizing number of logic elements, total fan-out, and total power dissipation for systems with varying number of processing elements.
