Chip having dual-mode device that switches between root complex mode and endpoint mode in different system stages and associated computer system
摘要：
A chip includes a peripheral component interconnect express (PCIe) switch, a dual-mode device, and a signal transmission control circuit. The PCIe switch includes a first downstream port. The dual-mode device switches between a root complex (RC) mode and an endpoint (EP) mode. The signal transmission control circuit is coupled between the PCIe switch and the dual-mode device. The first downstream port communicates with the dual-mode device operating under the EP mode. The signal transmission control circuit allows an external PCIe device to communicate with the dual-mode device operating under the RC mode.
