Low-power design method for wireless sensor network core chip

Abstract

The invention discloses a low-power design method for a wireless sensor network core chip. According to the low-power design method for the wireless sensor network core chip, the working mode of the chip is divided into a normal working mode and a low-power working mode, when the chip works in the normal working mode, the working frequency of the chip can be configured according to requirements of a specific application, and the clock frequency is reduced to save most dynamic power consumption due to unnecessary flipping of a clock; when the chip does not need to process tasks, the chip chooses to work in the low-power working mode, in the low-power working mode, the clock or power supplies in certain regions inside the chip can automatically turn off, and further the dynamic power consumption and the static power consumption are saved. According to the low-power design method for the wireless sensor network core chip, unnecessary power consumption can be reduced substantially whenever the chip works or sleeps, the service life of batteries is prolonged for wireless sensor network nodes, very important significance for power consumption reduction under the condition that the correct working of the wireless sensor network nodes is guaranteed is achieved.

Problems solved by technology

[0006] The reduction of power consumption at the RTL level is mainly achieved by reducing unnecessary jumps of registers. This jump will not affect the output of the circuit logic function, that is, the output value does not need to change while the circuit is jumping, resulting in The increase in power consumption
