Description:
The 16-bit
immediate
is sign-extended and compared to the contents of general register
rs
. Considering both
quantities as unsigned integers, if the contents of general register
rs
are greater than or equal to the sign-extended
immediate
, a trap exception occurs.
Operation:
32 T: if (0 || GPR [rs]) > (0 || (immediate
15
)
16
|| immediate
15...0
) then
TrapException
endif
64 T: if (0 || GPR [rs]) > (0 || (immediate
15
)
