Patent ID: 8451892

Claim:
A computer readable medium comprising instructions executable by a processor to perform a method, the method comprising: receiving a set of input data in a first matrix format; compressing the set of input data to obtain a first set of compressed data in a second matrix format, wherein compressing the set of input data comprises using a quantization equation, the quantization equation comprising: Yq ( i,j )=[( Y ( i,j )+offset)<< n]/qs, wherein Yq(i,j) represents a coefficient in a matrix of the first set of compressed data having a coordinate (i,j); Y(i,j) represents a coefficient in a matrix of the set of input data having the coordinate (i,j); offset is an integer; << is a first bit-wise shift operator; n is an integer; and qs is a real number; and sending the first set of compressed data to a first destination.
