摘要： A system on chip, an access command routing method, and a terminal are disclosed. The system on chip includes an IP core and a bus. The IP core is configured to: obtain, based on an access address corresponding to an access command, an address range configuration identifier corresponding to the access address; and transmit the access command and the address range configuration identifier to the bus, where the address range configuration identifier is used by the bus to route the access command. The bus is configured to route the access command to a system cache or an external memory based on the address range configuration identifier.

摘要： A first device obtains an advertising parameter used by a second device to send an advertising data packet, where the advertising parameter includes an advertising window and an advertising interval. The first device determines, based on the advertising window and the advertising interval by using a preset scanning model, a target scan parameter used by the first device, where the target scan parameter is a scan parameter used by the first device when power consumption of the first device is a preset threshold and a scan-to-discover time period satisfies a preset condition. The target scan parameter includes a target scan window and a target scan interval. The first device performs scanning based on the target scan window and the target scan interval.
