MACWH.D – Multiply Word with Halfword and Accumulate in Doubleword
Architecture revision:
Architecture revision1 and higher.
Description
Multiplies the word and halfword register specified and adds the result to the specified double-
word-register. The halfword register is selected as either the high or low part of Ry. Only the 48
highest of the 64 possible bits in the doubleword accumulator are used. The 16 lowest bits are
cleared.
Operation:
