Saturation GR[r]
Format:
Purpose: To test general register GR[r] 16-bit overflow, then saturate GR[r] into
G[t],
GR r and Gr t may be the same register
Description: To test general GR[r] 16-bit overflow, and if the general register GR[r]
is overflow, then saturate the general register GR[r], and the saturation result is put
into destination register Gr[t]. If Gr[r] is not overflow, the GR[r] value is copied into
GR[t].
operation, and the result is stored in GR r register. The operation tests the high-order
32-bits of the register GR[r], and the possible results after execution of saturation is
shown in TableI.
