Method and apparatus for controlling hardware device, electronic device and storage medium
Disclosed are a method and apparatus for controlling a hardware module, electronic device and storage medium. In an embodiment of the present disclosure, the method may include: timing a waiting state of the hardware module to obtain a current waiting duration of the hardware module when it enters a first waiting state; generating an interrupt signal based on the current waiting duration; determining program information corresponding to the current waiting duration under triggering from the interrupt signal; executing an action corresponding to the program information for the hardware module, and controlling it to enter a second waiting state. In the present disclosure, the hardware module is controlled to execute actions corresponding to different programs based on different waiting durations through an interrupt mechanism, thus controlling the hardware module to switch between waiting states with different power consumption, and achieving a good balance between energy saving and performance.
SYSTEMS AND METHODS FOR STABLE AND ELEVATED IDLE-MODE TEMPERATURE FOR ASSEMBLED SEMICONDUCTOR DEVICES
Disclosed herein are embodiments of systems and methods for stable and elevated idle-mode temperature for assembled semiconductor devices.

DATA FABRIC C-STATE MANAGEMENT
A data processor includes a plurality of requestors, a plurality of responders, and a data fabric. The data fabric is for routing requests between the plurality of requestors and the plurality of responders and has a plurality of non-operational power states including a normal C-state and a light-weight C-state. The light-weight C-state has lower entry and exit latencies than the normal C-state. The data fabric monitors traffic through the data fabric and places the data fabric in the light-weight C-state in response to detecting an idle traffic state.
Temperature restricted mode for cellular enhancement
A method, a device, and an integrated circuit utilizes a temperature restricted mode. The method includes determining a temperature of the device. When the temperature is below a first threshold, the method includes enabling a first mode comprising select network operations. When the temperature is above a brick threshold, the method includes enabling a second mode comprising disabling the select network operations. When the temperature is above the first threshold and below the brick threshold, the method includes enabling a third mode comprising modifying at least one of the select network operations.
Probe filter retention based low power state
A data fabric routes requests between the plurality of requestors and the plurality of responders. The data fabric includes a crossbar router, a coherent slave controller coupled to the crossbar router, and a probe filter coupled to the coherent slave controller and tracking the state of cached lines of memory. Power state control circuitry operates, responsive to detecting any of a plurality of designated conditions, to cause the probe filter to enter a retention low power state in which a clock signal to the probe filter is gated while power is maintained to the probe filter. Entering the retention low power state is performed when all in-process probe filter lookups are complete.
