  - In this work we present EvoCache, a novel approach for implementing application-specific
    caches. The key innovation of EvoCache is to make the function that maps memory
    addresses from the CPU address space to cache indices programmable. We support
    arbitrary Boolean mapping functions that are implemented within a small reconfigurable
    logic fabric. For finding suitable cache mapping functions we rely on techniques
    from the evolvable hardware domain and utilize an evolutionary optimization procedure.
    We evaluate the use of EvoCache in an embedded processor for two specific applications
    (JPEG and BZIP2 compression) with respect to execution time, cache miss rate and
    energy consumption. We show that the evolvable hardware approach for optimizing
    the cache functions not only significantly improves the cache performance for
    the training data used during optimization, but that the evolved mapping functions
    generalize very well. Compared to a conventional cache architecture, EvoCache
    applied to test data achieves a reduction in execution time of up to 14.31% for
    JPEG (10.98% for BZIP2), and in energy consumption by 16.43% for JPEG (10.70%
    for BZIP2). We also discuss the integration of EvoCache into the operating system
    and show that the area and delay overheads introduced by EvoCache are acceptable.
