MACHH.D – Multiply Halfwords and Accumulate in Doubleword
Architecture revision:
Architecture revision1 and higher.
Description
Multiplies the two halfword registers specified and adds the result to the specified doubleword-
register. Only the 48 highest of the 64 possible bits in the doubleword accumulator are used. The
16 lowest bits are cleared. The halfword registers are selected as either the high or low part of
the operand registers.
Operation:

If (Rx-part == t) then operand1 = SE(Rx[31:16]) else operand1 = SE(Rx[15:0]);
If (Ry-part == t) then operand2 = SE(Ry[31:16]) else operand2 = SE(Ry[15:0]);
(Rd+1:Rd)[63:16] ← (operand1 × operand2)[31:0] + (Rd+1:Rd)[63:16];
Rd[15:0] ← 0;
