The　lighting　system　posed　by　the　combination　of　solar　photovoltaic　power　generation　and　the　white　LED　illumination　is　an　optimal　environmental　energy-efficient　lighting　system　and　an　important　trend　of　development　in　the　future.　This　paper　is　focusing　on　the　solar　energy　and　the　municipal　power　complementary　LED　lighting　control　system,　and　the　research　based　on　the　paper　is　on　the　processor　-　the　core　component　of　its　controller　especially　in　low　power　state.　According　to　the　structural　and　actual　needs　of　the　system,　I　proposed　the　synopsis　for　the　processor,　presented　a　reduced　instruction　set,　and　completed　5-stage　pipeline　processor　design　with　peripherals.　After　finishing　RTL　design,　I　optimized　the　schematic　by　self　clock-gating　register　in　order　to　reduce　the　power　of　clock　tree.　Finally,　I　successfully　achieved　design　features　through　the　FPGA.　This　design　is　the　foundation　of　the　controller　integrated.
