  text: 'Mapping applications that consist of a collection of cores to FPGA accelerators
    and optimizing their performance is a challenging task in high performance reconfigurable
    computing. We present IMORC, an architectural template and highly versatile on-chip
    interconnect. IMORC links provide asynchronous FIFOs and bitwidth conversion which
    allows for flexibly composing accelerators from cores running at full speed within
    their own clock domains, thus facilitating the re-use of cores and portability.
    Further, IMORC inserts performance counters for monitoring runtime data. In this
    paper, we first introduce the IMORC architectural template and the on-chip interconnect,
    and then demonstrate IMORC on the example of accelerating the k-th nearest neighbor
    thinning problem on an XD1000 reconfigurable computing system. Using IMORC''s
    monitoring infrastructure, we gain insights into the data-dependent behavior of
    the application which, in turn, allow for optimizing the accelerator. '
