Specifying Run-time Reconfiguration in Processor Arrays using High-level language

The adoption of run-time reconfigurable parallel architectures for high-performance embedded systems is constrained by the lackof a unified programming model which can express both parallelism and reconfigurability. We propose to program an emerging class of reconfigurable processor arrays by using the programming model of occam-pi and describe how the extensions of channel direction specifiers, mobile data, dynamic process invocation, and process placement attributes can be used to express run-time reconfiguration in occam-pi. We present implementations of DCT algorithm to demonstrate the applicability of occam-pi to express reconfigurability. We concluded that occam-pi appears to be a suitable programming model for programming run-time reconfigurable processor arrays
