Abstract
Dynamic management method and system for an active state power management (ASPM) mechanism are provided. The method is applicable to a peripheral component interconnect express (PCIe) transmission architecture that includes a host and a PCIe downstream component. The method includes: configuring the PCIe downstream component to perform: determining whether data transmission status between a PCIe upstream component and the PCIe downstream component is in a busy state, a stable idle state or a temporary state; in response to determining that the data transmission status is in the busy state, forcibly disabling the ASPM function; in response to determining that the data transmission state is in the stable idle state, forcibly enabling the ASPM function; and in response to determining that the data transmission state is in the temporary state, determining whether the data transmission state is the busy state, the stable idle state or the temporary state again.
