Co-compression and co-decompression of data values

摘要

A first and a second data value are co-compressed by generating a sequence of symbols having a most significant symbol that is the most significant symbol of a compressed representation of the first data value and a least significant symbol that is the most significant symbol of a compressed representation of the second data value. The compressed representation of the first data value corresponds to at least a portion of the symbols of the sequence of symbols starting from the most significant symbol and extending towards the least significant symbol in a first reading direction. The compressed representation of the second data value also corresponds to at least a portion of the symbols of the sequence of symbols, however, starting from the least significant symbol and extending in an opposite reading direction towards the most significant symbol.

1. A data compressing method comprising:
co-compressing, by a data processing device coupled to a non-transitory memory, at least a first data value and a second data value by generating a sequence of symbols having a most significant symbol that is the most significant symbol of a compressed representation of said first data value and a least significant symbol that is the most significant symbol of a compressed representation of said second data value, wherein said compressed representation of said first data value comprises at least a portion of said sequence of symbols starting from said most significant symbol of said sequence of symbols and extending in a first reading direction towards said least significant symbol and said compressed representation of said second data value comprises at least a portion of said sequence of symbols starting from said least significant symbol and extending in a second, opposite reading direction towards said most significant symbol of said sequence of symbols; and storing, by the data processing device in the non-transitory memory, said sequence of symbols as a compressed representation of at least said first data value and said second data value.
