  • Patent number: 11720368
    Abstract: Techniques for memory management of a data processing system are described herein. According to one embodiment, a memory usage monitor executed by a processor of a data processing system monitors memory usages of groups of programs running within a memory of the data processing system. In response to determining that a first memory usage of a first group of the programs exceeds a first predetermined threshold, a user level reboot is performed in which one or more applications running within a user space of an operating system of the data processing system are terminated and relaunched. In response to determining that a second memory usage of a second group of the programs exceeds a second predetermined threshold, a system level reboot is performed in which one or more system components running within a kernel space of the operating system are terminated and relaunched.

  • Patent number: 8315191
    Abstract: Techniques for detecting mode and guard length and estimating timing offset for an OFDM transmission are described. Multiple hypotheses for different combinations of mode and guard length that might have been used for the OFDM transmission are evaluated. For each hypothesis, correlation is performed on received samples for a hypothesized guard interval to obtain correlation results. The energy of the hypothesized guard interval is determined. A first metric is derived based on the correlation results and the energy. The first metric may be filtered, e.g., averaged. Noise is estimated, e.g., based on a set of elements for the filtered first metric at locations determined by an estimated timing offset for the hypothesis. A second metric is derived based on the filtered first metric and the estimated noise. The second metric for all hypotheses may be used to determine the mode, guard length, and timing offset for the OFDM transmission.
