Patent ID: 7565022

Claim:
A method for encoding coefficients comprising: applying by a processor one or more wavelet transforms to generate a plurality of coefficients that describe horizontal and vertical spatial frequency characteristics of original tile-component planes; executing a special instruction by a processor to accelerate conversion of the plurality of coefficients into bit-planes by reducing the number of clock cycles required of the processor to convert the coefficients during compression, identify zero bit planes in the plurality of coefficients and generate a sign bit-plane, N bit-planes and N zero bit-planes of each of the plurality of coefficients in memory; in response to all bits in a plane being zero, storing by the processor an indicator in a N-bit zero register part of the memory corresponding to the N bit-planes of the plurality of coefficients being processed; and storing by the processor N bit-planes of each of the plurality of coefficients in memory in response to the instruction.
