SYNTAX
FUNCTION
DESCRIPTION
halfwords of rsrc1 and rsrc2; the two products are summed, and the result is written to rdest. All halfwords are
considered unsigned; thus, the intermediate products and the final sum of products are unsigned. All intermediate
computations are performed without loss of precision; the final sum of products is clipped into the range [0xffffffff..0]
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.
