Abstract: Systems and methods for improved operation of a victim cache in a portable computing device (PCD) are presented. A lower level cache is operated as a victim to an upper level cache, the lower level cache containing a plurality of cache lines. A filter is operated in association with the lower level victim cache, and reflects the cache lines contained in the victim cache. For a miss at the upper level cache, the filter is checked to determine if the requested cache line is in the victim cache. If checking the filter determines that the requested cache line is in the victim cache the requested cache line is retrieved from the victim cache. If checking the filter determines that the request cache line is not in the victim cache, the victim cache is bypassed and the cache line is requested from a memory controller.

Abstract: Systems and methods for forecasting behavior of caches include a hypothetical cache. The hypothetical cache is configured to emulate cache behavior, and performance metrics for the hypothetical cache are determined, where the performance metrics may be based on cache hits/misses. Performance metrics for a real cache of a processor core of a processing system may also be similarly determined. Behavior of the real cache is forecast based, at least, on performance metrics of the hypothetical cache, and in some cases, also on performance metrics of the real cache (e.g., based on a comparison of the performance metrics). Actions may be recommended and/or performed based on the forecast, where the actions include modifying the real cache size, associativity, or allocation for processor cores, migrating a task running in one processor cluster to another processor cluster, or for collecting data for the real cache for offline analysis.

Abstract: Systems and methods for adaptive implementation of victim cache modes in a portable computing device (PCD) are presented. In operation, an upper level cache is partitioned into a main portion and a sample portion; and a lower level cache is partitioned into a corresponding main portion and sample portion in communication with the main portion and sample portion of the upper level cache. A victim mode sample data set and a normal mode sample data set are obtained from the lower level cache. Based on the victim mode and a normal mode sample data sets, a determination is made whether to operate the lower level cache as a victim to the upper level cache. The main portion of lower level cache is caused to operate either as a victim or non-victim to the main portion of the upper level cache in accordance with the determination.

Abstract: The aspects include systems and methods of managing virtual memory page shareability. A processor or memory management unit may set in a page table an indication that a virtual memory page is not shareable with an outer domain processor. The processor or memory management unit may monitor for when the outer domain processor attempts or has attempted to access the virtual memory page. In response to the outer domain processor attempting to access the virtual memory page, the processor may perform a virtual memory page operation on the virtual memory page.

Abstract: Methods, systems and devices compute and use the actual execution states of software applications to implement power saving schemes and to perform behavioral monitoring and analysis operations. A mobile device may be configured to monitor an activity of a software application, generate a shadow feature value that identifies actual execution state of the software application during that activity, generate a behavior vector that associates the monitored activity with the shadow feature value, and determine whether the activity is malicious or benign based on the generated behavior vector, shadow feature value and/or operating system execution states. The mobile device processor may also be configured to intelligently determine whether the execution state of a software application is relevant to determining whether any of the monitored mobile device behaviors are malicious or suspicious, and monitor only the execution states of the software applications for which such determinations are relevant.
