Abstract
Systems and methods for predicting the compressibility of data in a flash storage device are provided. One such method involves extracting byte intervals from the block of data, each of the byte intervals consisting of a preselected number of bytes, performing a hash function to map the byte intervals into a plurality of bins, the plurality of bins comprising one bin for each possible value of the byte intervals, incrementing a hit count each time more than one of the byte intervals is mapped into a single bin of the plurality of bins, and determining whether to compress the block of data based on a comparison of a ratio of the hit count to a total number of the byte intervals and a preselected threshold. This method may be implemented in hardware to ensure fast and efficient execution.
