As fabrication technologies advance, increasing wire delays in semiconductor systems are leading to larger and larger gaps between the clock rates of circuits implemented in reconfigurable logic and those of conventional microprocessors. In this paper, we present a pipelining scheme for the Amalgam programmable-reconfigurable processor that divides long wire delays into multi-cycle operations and supports overlapping of independent computations. On streaming benchmark programs, this pipelining
