Abstract
Data element filter logic (“hardware accelerator”) in a processor that offloads computation for an in-memory database select/extract operation from a Central Processing Unit (CPU) core in the processor is provided. The Data element filter logic provides a balanced performance across an entire range of widths (number of bits) of data elements in a column-oriented Database Management System.
