shifting and saturating two 16 bit words packed in one register

Note: This was originally posted on 7th November 2010 at http://forums.arm.com

hi all. im using ARM1176JZF-S. im having two 16 bit words packed in one 32 bit register. i need to shift the two words left by 2 and saturate it.
for example: #0x7000A000 should become : #0x7FFF8000
i know i can use the ssat16 instruction , but it doesnt help me after the shifting.
does anyone have an idea?
thanks all
