We consider time slot interchangers (TSIs) which are built from 2Ã—2 exchange switches and delays and which are useful for time division multiplexed (TDM) systems in telecommunications and pipelined systems such as time multiplexed optical multiprocessors. We formulate a general method for constructing TSIs based on multistage interconnection networks in theâ€¦ (More)

We present a fast parallel solution method for the Poisson equation on irregular domains. Due to a simple embedding method using harmonic polynomial approximation, a dominant part of the computation becomes solving one Poisson problem on a disk.
