    • A boot system of an electronic device includes a central processing unit (CPU), a NAND flash, a synchronous dynamic random access memory (SDRAM), and a pulse count unit. The NAND flash and the SDRAM are electronically connected with the CPU. The pulse count unit is electronically connected with the CPU and the NAND flash. The pulse count unit may initialize and enable the NAND flash. The CPU reads a pre-boot loader stored in the NAND flash and loads the pre-boot loader in the SDRAM. The CPU executes the pre-boot loader stored in the SDRAM to boot the electronic device.
    • 电子设备的引导系统包括中央处理单元(CPU),NAND闪存,同步动态随机存取存储器(SDRAM)和脉冲计数单元。 NAND闪存和SDRAM与CPU电连接。 脉冲计数单元与CPU和NAND闪存电子连接。 脉冲计数单元可初始化并启用NAND闪存。 CPU读取存储在NAND闪存中的预引导加载程序,并将预引导加载程序加载到SDRAM中。 CPU执行存储在SDRAM中的预引导加载程序以引导电子设备。

    • An embedded system comprises a main chip generating a sleep signal, a network interface controller (MC) generating a wake-up signal, a microprogrammed control unit (MCU), a switch, and a power source. The MCU sends a closing signal upon receiving the wake-up signal and an opening signal upon receiving the sleep signal. The switch comprises a public terminal, a free terminal, and a control terminal. The free terminal connects to the main chip, the control terminal connects to the MCU, the public terminal connects to the free terminal upon receiving the closing signal, and the public terminal disconnects from the free terminal upon receiving the opening signal. The power source connects to the MC and the MCU to provide power, and further connects to the public terminal to provide power if the public terminal and the free terminal are connected, and stop power if disconnected.
    • 嵌入式系统包括产生睡眠信号的主芯片,产生唤醒信号的网络接口控制器(MC),微程序控制单元(MCU),开关和电源。 在接收到唤醒信号时,MCU发送闭​​合信号,并在接收到睡眠信号时发送打开信号。 交换机包括公共终端,免费终端和控制终端。 免费终端连接到主芯片,控制终端连接到MCU,公共终端在收到关闭信号时连接到免费终端,公共终端在接收到开启信号时与自由终端断开连接。 电源连接到MC和MCU提供电源,并且如果公共终端和免费终端连接,则进一步连接到公共终端以提供电力,并且如果断开连接则停止电力。
