Set on Less Than Unsigned

Purpose:

Set on Less Than Unsigned

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

Description: 

 GPR[rd] = (GPR[rs] < GPR[rt])

Compare the contents of GPR rs and GPR rt as unsigned integers; record the Boolean result of the comparison in

GPR rd. If GPR rs is less than GPR rt, the result is 1 (true); otherwise, it is 0 (false).

The arithmetic comparison does not cause an Integer Overflow exception.

Restrictions:

None

Operation: 

if (0 || GPR[rs]) < (0 || GPR[rt]) then
   GPR[rd] = 0GPRLEN-1 || 1
else
   GPR[rd] = 0GPRLEN
endif

Exceptions:

None
