—By strictly separating reconfigurable logic from the host processor, current custom computing systems suffer from a significant communication bottleneck. In this paper, we describe Chimaera, a system that overcomes the communication bottleneck by integrating reconfigurable logic into the host processor itself. With direct access to the host processor's(More)
—Carry chains are an important consideration for most computations, including FPGA's. Current FPGA's dedicate a portion of their logic to support these demands via a simple ripple carry scheme. In this paper, we demonstrate how more advanced carry constructs can be embedded into FPGA's, providing significantly higher performance carry computations. We(More)
In this paper we present an implementation of the image compression routine SPIHT in reconfigurable logic. A discussion on why adaptive logic is required, as opposed to an ASIC, is provided along with background material on the image compression algorithm. We analyzed several Discrete Wavelet Transform architectures and selected the folded DWT design. In(More)
