Application: Multi-processor device, data processing system and peripheral controller sharing method (Patent ID: US20240211267A1)
The patent filed by Winbond Electronics Corp. describes a multi-processor device that allows more than two processors running different operating systems to share a peripheral controller by allocating transmit and receive descriptions and buffers in a shared memory. This enables the processors to communicate with a peripheral device, such as an Ethernet network card, efficiently. The system peripheral configuration controller manages the allocation of the peripheral controller to the processors, ensuring seamless data transmission and reception.
The multi-processor device's method involves initializing the peripheral controller by the first processor, allocating device identifications to each processor, and facilitating communication between the processors via a specific transmission interface. The system ensures that data transmitted to the peripheral device is stored in the appropriate receive buffers based on device identification, allowing each processor to access the data efficiently. This innovative approach to sharing a peripheral controller among multiple processors enhances the device's overall performance and data processing capabilities, particularly in scenarios where different operating systems are involved.
