Oracle (Sun) latest CPUs support something called DAX (data analytics extension, not the same thing as the Intel DAX - direct access extensions). It's a coprocessor that allows offloading simpler operations closer to RAM, apparently: "DAX is an integrated co-processor which provides a specialized set of instructions that can run very selective functionality – Scan, Extract, Select, Filter, and Translate – at fast speeds. The multiple DAX share the same memory interface with the processors cores so the DAX can take full advantage of the 140-160 GB/sec memory bandwidth of the SPARC M7 processor." https://blogs.oracle.com/bestperf/accelerating-spark-sql-using-sparc-with-dax%2c-16x-faster-per-core-over-and-above-spark-210-with-tungsten https://blogs.oracle.com/bestperf/accelerating-spark-sql-usi...
