A novel low buffered optimized Solid State Drive controller

In this paper, a novel algorithm to reduce the intermediate buffer size of a Solid State Drive (SSD) controller has been proposed. The algorithm implements compression and encryption to reduce the stored data and secure it. The cyclic operation of compression and encryption reduces the intermediate buffer size substantially compared to serial operation. The algorithm has been optimized and tested for different standards of Xtensa processor and the best suitable standard has been reported in terms of processor cycles.
