In this paper, I have studied various hardware solutions for sorting. The circuitry at the processor level responsible for sorting has been identified; its role and different modifications possible to accelerate sorting have been discussed. Some application-specific circuitry has also been studied, this circuitry can be based on comparator and swap circuitry as in sorting networks or non-comparator based hardware solutions. In addition to this, the extension of the instruction set of the processors to incorporate software instructions to implement sorting has also been studied.
