对于传统乘用车而言,油箱是唯一的实际能源来源,故制造商们寻求在包括电子系统在内的所有汽车系统中节能,以进一步改善燃油经济性及二氧化碳(CO2)排放。随着汽车中增添的电子系统的数量不断增多,如果汽车中每个电子控制单元(ECU)的节能效果较低,就会使总油耗大幅增加。芯片设计人员采用不同技术及途径,已经能够降低他们提供的器件的总能耗。在单个系统基础芯片(SBC)中结合多个器件的功能,并应用不同电源管理策略,还能帮助进一步降低总能耗。
For conventional passenger cars, the fuel tank is the only real source of energy, so manufacturers seek to save energy in all automotive systems, including electronic systems, to further improve fuel economy and carbon dioxide (CO2) emissions. As the number of electronic systems added to automobiles continues to increase, the overall fuel consumption will increase significantly if the energy savings of each electronic control unit (ECU) in the car are low. By using different technologies and approaches, chip designers have been able to reduce the total power consumption of the devices they provide. Combining the capabilities of multiple devices in a single system-on-chip (SBC) and applying different power management strategies can help further reduce overall energy consumption.
