Abstract: A program is executed using a call stack and shadow stack. The call stack includes frames having respective return addresses. The frames may also store variables and/or parameters. The shadow stack stores duplicates of the return addresses in the call stack. The call stack and the shadow stack are maintained by, (i) each time a function is called, adding a corresponding stack frame to the call stack and adding a corresponding return address to the shadow stack, and (ii) each time a function is exited, removing a corresponding frame from the call stack and removing a corresponding return address from the shadow stack. A backtrace of the program's current call chain is generated by accessing the return addresses in the shadow stack. The outputted backtrace includes the return addresses from the shadow stack and/or information about the traced functions that is derived from the shadow stack's return addresses.

Abstract: Methods and apparatus for optimizing device power and efficiency based on host-controlled hints prior to low-power entry for PCI Express blocks and components. Data structures containing low-power state capability information mapping one or more fine-grained low-power states for each of at least one of an L0s, L1, L1.1, and L1.2 PCIe-defined low-power state are stored on a PCIe device coupled to a Host via a PCIe link. Messages are exchanged over the PCIe link between the Host and PCIe device to configure, using the low-power state capability information, blocks and/or components on the PCIe device to enter a fine-grained low-power state instead of an associated PCIe-defined low-power state mapped to the fine-grained low-power state when the PCIe device detects a power-change event or receives a command to enter the associated PCIe-defined low-power state. Sequences of power-level changes between multiple fine-grained low-power states may also be implemented.

Abstract: A multi-level memory architecture scheme to dynamically balance a number of parameters such as power, thermals, cost, latency and performance for memory levels that are progressively further away from the processor in the platform based on how applications are using memory levels that are further away from processor cores. In some examples, the decision making for the state of the far memory (FM) is decentralized. For example, a processor power management unit (p-unit), near memory controller (NMC), and/or far memory host controller (FMHC) makes decisions about the power and/or performance state of the FM at their respective levels. These decisions are coordinated to provide the most optimum power and/or performance state of the FM for a given time. The power and/or performance state of the memories adaptively change to changing workloads and other parameters even when the processor(s) is in a particular power state.

By this way, the BS can measure the signal intensities of the neighboring BSes by itself, and controls the UE to handover at an appropriate neighboring BS signal intensity.

Abstract: A method for tracking and positioning a magnetic catheter and a structure of a magnetic catheter are disclosed for facilitating tracking and positioning of catheters in human bodies without using electromagnetic induction as conventionally used. When electromagnetic induction and remote magnetic control are used together, their respective magnetic fields may mutually interfer, increasing the risk of operational errors of the magnetic catheters they are working on. The disclosed magnetic catheter has an elastic unit. While the magnetic catheter bends, inductance variation caused by elastic deformation of the elastic unit is measured for calculating an actual bending angle of the magnetic catheter. Then the motion of the magnetic catheter can be amended accordingly. By using calculation instead of electromagnetic tracking, mutual interference between different magnetic fields can be prevented.

Abstract: A method for controlling a magnetic catheter by using a magnetic-field-generated magnetic annulus is disclosed. The magnetic catheter has a free end provided with a magnetic member. A resultant magnetic field between at least two magnets generates a magnetic annulus. The magnetic catheter is placed into the magnetic annulus, so that the magnetic member is affected by the magnetic force from the magnetic annulus to guide the magnetic catheter to perform a preset motion. The magnetic catheter has a flexible front section, so that the flexible section can perform a bending motion when led by the magnetic member. The resultant magnetic field is generated by arranging the two magnets with their like poles facing each other, so that the magnetic member is thrust when entering the magnetic annulus. This facilitates the bending motion of the flexible section.
