利用年龄编码的Bloom过滤算法降低Load-Store队列功耗

An Age Encoding Based Bloom Filter Algorithm for Load-Store Queue Energy Reduction

考虑Load-Store顺序违例和多线程及多处理器中的Load-Load顺序违例,对基于计数器的Bloom过滤算法进行改进,采用指令年龄编码消除过滤算法引起的错误判定,在不对流水线时序和性能产生影响的情况下,将过滤比率提高了5%以上。

The load-store order violations and load-load order violations are considered in muhithreaded or muhiprocessor systems, and the counter-based bloom filter algorithm is improved by eliminating false positives through age encoding. The filtering ratio is improved by over 5 % with no impacts on pipeline timing or performance.
