An universal design of low-power processor based on LED lighting control system by using solar cells

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.
