Reconfigurable Custom Computers are being proposed as faster means of devices for Application specific computing. A key difference between the classical computer and a Reconfigurable custom computer is that a classical computer solves a problem with the available hardware and / or logic whereas a custom computer solves the problem with specialized hardware and / or logic. As an emerging field Reconfigurable Custom Computing is emerging as an important new organizational structure for implementing computations on the best-fit hardware and / or best-fit logic. It combines the post-fabrication programmability of processors with the spatial computational style most commonly employed in hardware and logic designs. The result changes traditional “hardware ” and / or “software ” boundaries, providing an opportunity for greater computational capacity and density within a programmable media. Reconfigurable Computing must leverage traditional CAD technology for building spatial designs. Specifically we are interested in questions: Can a Reconfigurable custom computer be Applicable to every problem where a classical computer can be used? Is it a costly affair to
