Set on Less Than Immediate Unsigned (Extended)

Purpose:

Set on Less Than Immediate Unsigned (Extended)

To record the result of an unsigned less-than comparison with a constant.

Description: 

T = (GPR[rx] < immediate)

The 16-bitimmediate is sign-extended and subtracted from the contents of GPR rx. Considering both quantities as unsigned integers, if GPR rx is less than the sign-extended immediate, the result is set to 1 (true); otherwise, the result is set to 0 (false). The result is placed into GPR 24.

Restrictions:

None

Operation: 

if (0 || GPR[Xlat(rx)]) < (0 || sign_extend(immediate)) then
   GPR[24] = 0GPRLEN-1 || 1
else
   GPR[24] = 0GPRLEN
endif

Exceptions:

None
