Abstract
A dual-processor system includes a power supply, a temporary memory, a non-volatile memory and two processors. The non-volatile memory stores an initialization program code, a first configuration file corresponding to a first operating system, and a second configuration file corresponding to a second operating system. Compared to the first operating system, the second operating system has a shorter interrupt latency and a shorter thread switching latency. After the power supply starts to supply power, the first processor executes the initialization program code to perform operations of initializing the temporary memory, loading the second configuration file into the temporary memory, notifying the second processor to fetch the second configuration file from the temporary buffer, loading the first configuration rile into the temporary memory and establishing the first operating system according to the first configuration file.
