Power saving techniques in computing devices

摘要

Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

主权项

1. A mobile terminal comprising:
a modem timer; a modem processor, the modem processor configured to hold modem processor to application processor data until expiration of the modem timer; an application processor; an interconnectivity bus communicatively coupling the application processor to the modem processor; and the application processor configured to hold application processor to modem processor data until triggered by receipt of the modem processor to application processor data from the modem processor through the interconnectivity bus after which the application processor to modem processor data is sent to the modem processor through the interconnectivity bus responsive to the receipt of the modem processor to application processor data from the modem processor through the interconnectivity bus.
