Systems, apparatus and methods are provided for determining whether data associated with a command in a storage system is hot or cold. An apparatus may comprise a first interface to be coupled to a host and circuitry configured to receive a command via the first interface from the host. The command may contain an address for data storage in a data storage system and a length for a size of data associated with the command. The circuitry may be further configured to classify the command into a cluster of a plurality of clusters, obtain a plurality of historical commands in the cluster and determine whether the data associated with the command is hot or cold using a machine learning model. The address and the length of the command and addresses and lengths of the plurality of historical commands may be used as input features to the machine learning model.

Systems and methods for a data storage system

Systems, apparatus and methods are provided for compressing data. A method may include receiving an input data block to be compressed, determining numbers of occurrences for distinct symbols in the input data block, generating reduced numbers of occurrences for the distinct symbols based on the numbers of occurrences for the distinct symbols and encoding the input data block using the reduced numbers of occurrences as probability distribution of the distinct symbols in the input data block.

Data compression using reduced numbers of occurrences

Systems, apparatus and methods are provided for compressing data and decompressing compressed data. A method may comprise receiving an input data block to be compressed, generating a number of occurrences table and a cumulative occurrences table for distinct symbols in the input data block, for each symbol in the input data block, based on the number of occurrences table and the cumulative occurrences table, dynamically obtaining a number of shifts for right-shifting a current state 'x' to encode a current symbol, outputting right-shifted bits to encoded data and obtaining a next state 'x' and obtaining a final state &#x201c;X&#x201d; from a last state &#x201c;x&#x201d; generated in a final loop.

Hardware friendly data compression

The present disclosure relates to methods and systems for decoding a Bose-Chaudhuri-Hocquenghem (BCH) encoded codeword. The methods-may include receiving a codeword over a data channel; determining a plurality of syndrome values for the codeword during a first time interval; determining a set of initial elements during the first time interval; generating an error locator polynomial based on the plurality of syndrome values, the error locator polynomial representing one or more errors in the codeword; evaluating, based on the set of initial elements, the error locator polynomial to identify one or more error locations corresponding to the one or more errors in the codeword; and correcting the codeword based on the one or more error locations.
