Raw Blame History

; This test checks the effect of the index looping registers (R8-R11)
incdir "tests"
include "dsp_base.inc"
; First theories, fitting tests with nice masks in the loop registers
; IR THEORY: if ((ar & lp) == lp) ar &= ~lp;
; DR THEORY: if ((ar & lp) == 0) ar |= lp;
; These were proven FALSE though by the following:
; Tests done using AR1 = 0x0010, IX1 = 0
; WR1 = 0
; 10, 11, 11, 11, 11......
; WR1 = 1
; 10, 11, 10, 11, 10......
; WR1 = 2
; 10, 11, 12, 13, 11, 12, 13, 11, 12, 13 ......

; 10, 11, 12, 13, 10, 11, 12, 13, 10, 11, 12, 13.......

; And thus it's tricky to implement in software too :p
