    GP32 Some Tricks For Division

    I'd replace the first loop by this (untested, no ARM at hand :-) cmp r1,r3,lsr #16 movls r2,r1,lsl #16 movhi r2,r1 cmp r2,r3,lsr #8 movls r2,r2,lsl #8 cmp r2,r3,lsr #4 movls r2,r2,lsl #4 cmp r2,r3,lsr #2 movls r2,r2,lsl #2 cmp r2,r3,lsr #1 movls r2,r2,lsl #1 Which does omit the...

    GP32 Some Tricks For Division

    And: If you have to divide with a constant or many times thru the same value, computing the reciprocal may help: a/b = a * 1/b // compute the 1/r1 // destroy r2,r3 mov r2,r1 cmp r2,#0x00010000 movlo r2,r2,lsl #16 cmp r2,#0x01000000 movlo r2,r2,lsl #8 cmp r2,#0x10000000 movlo r2,r2,lsl...
