【摘要】 在便携式心电监护仪器设计中,微处理器是影响系统功耗的重要因素,可以通过对微处理器内部资源的设计来降低整个系统的功耗.C8051F040单片机是一低电压供电(2.7～3.6V),集成度更高,运行速度更快的8位CIP51处理器,因此C8051F040单片机在低功耗系统设计中具有很大优势,在便携式心电监护仪的设计中,我们采取了一系列的硬件和软件措施,系统功耗降低了近30%.更多还原

【Abstract】 In the design of portable ECG monitor,MCU is an important factor influences the power consumption of the system,so choosing a low power MCU is very important to reduce the system power consumption.The C8051F040 is a MCU with low power supply,high integration,high-speed 8-bit CIP51 core,so it has great advantages in low-power system design.In our system,we take some hardware and software measures to lower the power consumption,the power consumption reduction close to 30 %.更多还原
