Abstract: The feature size of semiconductor devices continues to decrease in each new generation. Smaller channel lengths lead to increased leakage currents. To reduce leakage current, some power domains within a device may be powered off (e.g., power collapsed) during periods of inactivity. However, when power is returned to the collapsed domains, circuitry in other power domains may experience significant processing overhead associated with reconfiguring communication channels to the newly powered domains. Provided in the present disclosure are exemplary techniques for isolating power domains to promote flexible power collapse while better managing the processing overhead associated with reestablishing data connections.

Abstract: Methods and systems may include a human interface device (HID) and logic to place the HID in a blocked state in response to a request to power off the system. The logic can also use a speculative start-up heuristic to establish one or more subsequent operating states for the system while the HID is in the blocked state, wherein the background automatic state transitions may maximize battery life when a user is not present. In addition, the HID may be removed from the blocked state in response to a request to power on the system. Accordingly, the speculative start-up heuristic can make system “ready-to-use” before the user actually interacts with any inputs (e.g. power button, or touch screen) of the system.

Abstract: Multi-step programming of heat-sensitive non-volatile memory (NVM) in processor-based systems, and related methods and systems are disclosed. To avoid relying on programmed instructions stored in heat-sensitive NVM during fabrication, wherein the programmed instructions can become corrupted during thermal packaging processes, the NVM is programmed in a multi-step programming process. In a first programming step, a boot loader comprising programming instructions is loaded into the NVM. The boot loader may be loaded into the NVM after the thermal processes during packaging are completed to avoid risking data corruption in the boot loader. Thereafter, the programmed image can be loaded quickly into a NV program memory over the peripheral interface using the boot loader to save programming time and associated costs, as opposed to loading the programmed image using lower transfer rate programming techniques. The processor can execute the program instructions to carry out tasks in the processor-based system.
