Format:

SLT rd, rs, rt

Description:

The contents of general register

rt are subtracted from the contents of general register rs. Considering both

quantities as signed integers, if the contents of general register

rs are less than the contents of general register rt,

the result is set to one; otherwise the result is set to zero.

The result is placed into general register

rd.

No integer overflow exception occurs under any circumstances. The comparison is valid even if the subtraction

used during the comparison overflows.

Operation:

if GPR [rs] < GPR [rt] then

GPR [rd] <- 0

31 || 1

else

GPR [rd] <- 0

endif

if GPR [rs] < GPR [rt] then

GPR [rd] <- 0

63 || 1

else

GPR [rd] <- 0

endif

Exceptions:

None
