Abstract
A storage infrastructure, method and encoder device for implementing low complexity encoding, The described encoder includes: a preprocessing system that assigns a code length to each unique symbol based on the frequency without performing a sort operation and determines maximum and minimum occurrence frequencies of symbols of each given code length, and the maximum and minimum code length among all the symbols; and a post processing system that cycles through each code length, determines if a maximum occurrence frequency of a current code length, associated with a first symbol, is greater than a minimum occurrence frequency of an adjacent code length, associated with a second symbol, and if greater, swaps code lengths of the first and second symbols.
