Abstract: An image processing accelerator device includes a memory, a decoder circuit, an event monitor circuit and a filter control circuit. The memory receives a first command corresponding to a task, and a wait event command which follows the first command. The decoder circuit decodes the first command and the wait event command to determine a register to be accessed in an image processing circuit and first data to be written by the first command, and generates an event identifier. The event monitor circuit determines according to the event identifier whether the image processing circuit has finished executing the task, and accordingly controls the image processing circuit to execute a command corresponding to a next task. The filter control circuit records second data previously stored in the register, and writes the first data to the register when the first data is different from the second data.

Abstract: Implementations of the present disclosure relate to detection of an untrusted configurator. In the implementations, an access point (AP) receives enrollee authentication information simulated by the network device from a network device. Then, the AP simulates an enrollee and broadcasts a configuration request including the enrollee authentication information. When a configurator responds to the configuration request, the AP identifies the configurator as an untrusted configurator, and then the AP transmits device information of the untrusted configurator to the network device. In this way, the untrusted configurator in the serving range can be detected, thereby avoiding the devices being provisioned to connect to untrusted networks.
