    摘要: A dual-processor electronic device is provided. The dual-processor electronic device includes a first processor, a second processor and a dynamic random access memory. The first processor sends a wake-up command to the second processor to wake up the second processor after performing local initialization. The second processor wakes up, then performs local initialization, copies and decompresses the image file to the dynamic random access memory and sends a ready message to the first processor after the image file is decompressed. The first processor delays startup, and starts the startup process according to the decompressed image file when the ready message is received and the delay-start time is expired. The present disclosure also provides a method for booting up dual-processor electronic device quickly.

    摘要: A branch-line coupler suitable for use in mobile devices includes a first, second, third, and fourth ports, respectively acting as input, transmitted, coupled, and isolated port. A first, second, third, and fourth connection parts are connected to the ports and transmission lines. First and second bent transmission lines are electrically connected between first and second ports. Third and fourth bent transmission lines are electrically connected between third and fourth ports. A first long strip transmission line is electrically connected between the first port and the fourth port. A second long strip transmission line is electrically connected between the second port and the third port. The branch-line coupler occupies a small area and has high performance.

    摘要: A firmware updating method in just a bunch of disks includes the following blocks. A motherboard is coupled to a first primary storage extension chip or to a second primary storage extension chip. The first primary storage extension chip and the second primary storage extension chip are coupled to each other. At least one secondary storage extension chip is coupled to the first primary storage extension chip. At least one secondary storage extension chip is coupled to the second primary storage extension chip. A signal sent to the first primary storage extension chip or to the second primary storage extension chip by the motherboard causes firmware of each storage extension chip to be updated.
