METHOD FOR DATA MANAGEMENT

摘要

A method for data management adapted for a host controller to store device context data of a universal serial bus (USB) device is provided, and the host controller includes a memory. The method includes following steps: storing a device slot index table in the memory; allocating a plurality of memory blocks in the memory according to state information of the USB device when it is detected that the USB device is coupled to the host controller, so as to store the device context data of the USB device, and storing an initial address of the memory blocks in the device slot index table; and releasing the memory blocks and erasing the initial address of the memory blocks stored in the device slot index table when it is detected that the USB device is detached from the host controller.

1. A method for data management, adapted for a host controller to store device context data of at least one universal serial bus (USB) device, wherein the host controller includes a memory, the method comprising following steps:
storing a device slot index table in the memory; allocating a plurality of memory blocks in the memory according to state information of a first USB device of the USB device when the first USB device coupled to the host controller is detected, so as to store the device context data of the first USB device, and storing an initial address of the memory blocks in the device slot index table; and releasing the memory blocks and erasing the initial address of the memory blocks from the device slot index table when the first USB device is detected being detached from the host controller.
