Abstract
Methods and decoding units for decoding a compressed data structure to determine a decoded value. The compressed data structure encodes a set of Haar coefficients for a block of pixels, including a plurality of differential coefficients and a sum coefficient. The compressed data structure includes a set of exponent bits representing exponents of the differential coefficients, a set of sign bits representing signs for the differential coefficients, a set of sum bits representing the sum coefficient. The compressed data structure is unpacked to identify the set of exponent bits, the set of sign bits and the set of sum bits. The identified set of exponent bits is used to determine exponents for the differential coefficients. The identified set of sign bits is used to determine signs the differential coefficients. The identified set of sum bits is used to determine the sum coefficient. The decoded value is determined by determining the result of a weighted sum of the differential coefficients and the sum coefficient for the block of pixels.
