A system comprising a memory and wavelet processing logic is described. The memory
is sized to include lines to store a band of an image and additional lines. The
wavelet processing logic comprises a wavelet transform and access logic. The wavelet
transform generates coefficients when applied to data in the memory. The access
logic reads data from the memory into the line buffers to supply data stored in
the memory to the wavelet transform and to store coefficients in the memory, such
that after data stored at a first pair of lines is read from memory into the buffers
of the access logic. The access logic reuses the first pair of lines to store coefficients
generated by the wavelet transform that are associated with a second pair of lines
different from the first pair of lines.
