Description:
immediate
The 16-bit
Considering both quantities as unsigned integers, if
result is set to one; otherwise the result is set to zero.
The result is placed into general register
Since the RSP does not signal an overflow exception for SLTI, this command behaves identically to
SLTI.
Operation:
T: if (0 || GPR[rs]) < (immediate
GPR[rd]  0
