1. A method of image compression in a digital data processor having a CPU that is coupled to an associated GPU comprising the steps of:

  • A. transforming, with the GPU, image values from a color representation to a frequency-based representation,B. with the GPU, re-ordering coefficients comprising the frequency-based representation such that coefficients of like order from multiple sub-blocks of the frequency-based representation of the image are ordered together,C. transferring the re-ordered coefficients to the CPU, the CPU at least one of storing and transmitting said coefficients.
