MULSATRNDWH.W – Multiply Word and Halfword with Saturation and
Rounding into Word
Architecture revision:
Architecture revision1 and higher.
Description
Multiplies the word register with the halfword register specified, rounds the upper 32 bits of the
result and stores it in the destination word-register. The halfword register is selected as either
the high or low part of Ry. Since the most significant part of the product is stored, no overflow will
occur. If the two operands equals -1, the result is saturated to the largest positive 32-bit fractional
number.
