SATS – Saturate Signed
Architecture revision:
Architecture revision1 and higher.
Description
This instruction considers the value in (Rd>>sa)[bp-1:0] as a signed value. If the value in
(Rd>>sa)[31:bp] is not merely a sign-extention of this value, overflow has occurred and satura-
tion is performed to the maximum signed positive or negative value. If saturation occurs, the Q
flag is set. An arithmetic shift is performed on Rd. If bp equals zero, no saturation is performed.
