Dual clipped add of signed 16-bit halfwords
SYNTAX
FUNCTION
DESCRIPTION
pairs of high and low 16-bit halfwords of rsrc1 and rsrc2. Both sums are clipped into the range [2
[0x7fff..0x8000]) and written into the corresponding halfwords of rdest. All values are signed 16-bit integers.
the modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 0x12340032, r40 = 0x00010002
r10 = 0, r30 = 0x12340032, r40 = 0x00010002
r20 = 1, r30 = 0x12340032, r40 = 0x00010002
r50 = 0x80000001, r80 = 0xffff7fff
r110 = 0x00017fff, r120 = 0x7fff7fff
