Abstract: A storage circuit includes a first storage region, a second storage region, a third storage region, and a fourth storage region. The first storage region stores first firmware data. The second storage region stores second firmware data. The third storage region stores first state data corresponding to the first firmware data. The fourth storage region stores second state data corresponding to the second firmware data. One of the first firmware data and the second firmware data is executed based on the first state data and the second state data. In a situation that the first firmware data is executed, the second firmware data is updated if a firmware updating event occurs.

Abstract: A firmware upgrade method and a firmware upgrade system based on a multi-stream transmission mode of a DisplayPort interface are provided. The firmware upgrade method includes: configuring a host to obtain firmware information of the displays through a DisplayPort auxiliary channel, and select a target display for firmware upgrade; and executing a firmware upgrade process including: configure the host to send a upgrade start command and firmware upgrade data to the target display; and configuring each display to: determine whether the upgrade start command and the firmware upgrade data reach the target display, and if not, send the upgrade start command and the firmware upgrade data to the next display, if so, execute a firmware upgrade preparation process according to the upgrade start command, and write the firmware upgrade data into the firmware storage device of the target display.

Abstract: An embedded system includes a host controller circuit and a microcontroller circuit. The host controller circuit is configured to access a storage device to obtain an address of a first firmware file in the storage device. The microcontroller circuit is configured to determine whether a memory circuit is being accessed by other circuits, in which the memory circuit includes memory blocks. If the memory circuit is not being accessed by the other circuits, the microcontroller circuit is further to control the host controller circuit to write the first firmware file to a first block of the memory blocks according to the address.

Abstract: A system capable of upgrading a firmware in the background and a method for upgrading a firmware in the background are provided. The method for upgrading the firmware in the background partitions the memory module of an electronic device, one user code sector is used to normally execute an initial firmware and an upgrade flow, and the other user code sector is used to store an upgrade firmware.
