ABSS
Absolute Value with Saturation
Description
Put the absolute value of data register D[b] in data register D[c]; If the contents of D[b] are greater than or equal
to zero, then copy it to D[c]; otherwise change the sign of D[b] and copy it to D[c]. The operands are treated as
signed, 32-bit integers, with saturation on signed overflow.
If D[b] = 80000000
H
(the maximum negative value), then D[c] = 7FFFFFFF
H
.
ABSSD[c], D[b] (RR)
result = (D[b] >= 0) ? D[b] : (0 - D[b]);
D[c] = ssov(result, 32);
