MULSATRNDHH.H – Multiply Halfwords with Saturation and Rounding into
Halfword
Architecture revision:
Architecture revision1 and higher.
Description
Multiplies the two halfword registers specified, shifts the results one position to the left and
stores the result in the destination word-register. If the two operands equal -1, the result is satu-
rated to the largest positive 16-bit fractional number. The halfword registers are selected as
either the high or low part of the operand registers. The product is rounded.

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]);
