MACSATHH.W – Multiply-Accumulate Halfwords with Saturation into Word
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 as a temporary word-sized product. If the two operands equals -1, the product
is saturated to the largest positive 32-bit fractional number. The halfword registers are selected
as either the high or low part of the operand registers. The temporary product is added with sat-
uration to Rd.
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]);
If (operand1 == operand2 == 0x8000)
