Variants

Mul6464NoSum
[−]

Walking 1 or more of J loop, doing r=a*b using 64x64=128

Mul6464Sum
[−]

Walking 1 or more of J loop, doing c,r=r+a*b using 64x64=128, but assume inner j loop

Mul6464FullSum
[−]

Walking 1 or more of J loop, doing c,r=r+a*b using 64x64=128, but sum all of w.

Mul6464Reduce
[−]

Walking 1 or more of J loop, doing c,r[-1]=r+a*b using 64x64=128, but skip 1st write

Add64
[−]

Walking add with off_AB, and in/out off_RES doing c,r=r+a+c using 64+64=65

Sub64
[−]

Walking subtract with off_AB, and in/out off_RES doing r=r-a uding 64-64=64, with last borrow implicit if any

Double64
[−]

Walking add to self with off_RES doing c,r=r+r+c using 64+64=65

Xor64
[−]

Walking XOR with off_AB, and in/out off_RES doing r=r^a using 64^64=64

ShiftLeft32
[−]

Walking shift left doing r1,r=(b*D)|r1, where D is 2^amt and is loaded by app (off_CD not used)

ShiftRight32
[−]

Walking shift right doing r,r1=(b*D)|r1, where D is 2^(32-amt) and is loaded by app (off_CD not used) and off_RES starts at MSW

Copy
[−]

Copy from ABoff to resoff, 64b at a time

Remask
[−]

Copy and mask from ABoff to resoff, 64b at a time

Compare
[−]

Compare two arrays, running all the way to the end

CompareFast
[−]

Compare two arrays, stopping on 1st !=^
