The　Network-on-Chip　(NoC)　has　been　recognized　as　a　paradigm　to　solve　System-on-Chip　(SoC)　design　challenges.　The　routing　algorithm　is　one　of　key　researches　of　a　NoC　design　XY　routing　algorithm,　which　is　a　kind　of　distributed　deterministic　routing　algorithms,　is　simple　to　be　implemented.　Odd-Even　(OE)　routing　algorithm,　whose　implementation　is　complex,　is　a　sort　of　distributed　adaptive　routing　algorithms　with　deadlock-free　ability.　We　demonstrate　the　two　routing　algorithms　in　details　at　first.　XY　routing　algorithm　and　OE　routing　algorithm　are　then　simulated　and　compared　based　on　a　3X3　mesh　topology　NoC　with　NIRGAM　simulator.　The　simulation　results　show　that　OE　routing　algorithm,　whose　P　parameter　equals　to　1.09,　increases　P　parameter　greatly　as　compared　to　XY　routing　algorithm,　whose　P　parameter　equals　to　0.86,　in　a　2-dimension　3X3　mesh　topology　NoC,　with　Constant　Bit　Rate　(CBR)　traffic　condition　of　each　tail.
