Format:
TGEI rs, immediate
Description:
The 16-bit
immediate
is sign-extended and compared to the contents of general register
rs
. Considering both
quantities as signed 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 GPR [rs] > (immediate15)16 || immediate15...0 then

TrapException
endif

64 T: if GPR [rs] > (immediate15)48 || immediate15...0 then

TrapException
endif
Exceptions:
