Sum of products of signed 16-bit halfwords
SYNTAX
FUNCTION
DESCRIPTION
halfwords of rsrc1 and rsrc2; the two products are summed, and the result is written to rdest. All values are considered
signed; thus, the intermediate products and the final sum of products are signed. All intermediate computations are
performed without loss of precision; the final sum of products is clipped into the range [0x80000000..0x7fffffff] before
being written into rdest.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 0x00020003, r40 = 0x00010002
r10 = 0, r60 = 0xff9c0064, r70 = 0x0064ff9c
r20 = 1, r60 = 0xff9c0064, r70 = 0x0064ff9c
r30 = 0x00020003, r70 = 0x0064ff9c
