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