; Instead of doing the transforms stage by stage, it is done by loading
; some input values and doing as many stages as possible to minimize the
; storing/loading of intermediate results. To fit within registers, the
; final coefficients are cut into four blocks:
; BLOCK A: 16-19,28-31
; BLOCK B: 20-23,24-27
; BLOCK C: 8-11,12-15
; BLOCK D: 0-3,4-7
; Blocks A and C are straight calculation through the various stages. In
; block B, further calculations are performed using the results from
; block A. In block D, further calculations are performed using the results
; from block C and then the final calculations are done using results from
; block A and B which have been combined at the end of block B.
