W (2007) An optimized message passing framework for parallel implementation of signal processing applications

Novel reconfigurable computing platforms enable effi-cient realizations of complex signal processing applications by allowing exploitation of parallelization resulting in high throughput in a cost-efficient way. However, the design of such systems poses various challenges due to the complexi-ties posed by the applications themselves as well as the het-erogeneous nature of the targeted platforms. One of the most significant challenges is communication between the various computing elements for parallel implementation. In this paper, we present a communication interface, called the signal passing interface (SPI), that attempts to overcome this challenge by integrating relevant properties of two dif-ferent yet important paradigms in this context — dataflow and the message passing interface (MPI). SPI is targete
