SLTU rd, rs, rt

Set on Less Than, Unsigned

Purpose:

Set on Less Than, Unsigned. Set the register $rd to 1 if unsigned register $rs is less thanunsigned register $rt, and 0 otherwise.

Operation: 

GPR[rd] = 1 if unsigned(GPR[rs]) < unsigned(GPR[rt]) else 0

SLTU encodings with rd=0 are used for the DVP and EVP instructions. DVP and EVP are required to behave as NOPs on cores without Virtual Processor (VP) support. This means that no DVP/EVP special

casing is required in hardware for non-VP cores,since a SLTU instruction writing to $0 naturally behaves as a NOP.

Exceptions:

None.
