The present disclosure provides a centralized power meter for a signal processing circuit, comprising: M sample buffers, each configured to buffer samples respectively from at least one of N sources, and trigger a request for power calculation of the buffered samples in response to the buffered samples, the request having a corresponding priority; a switch, configured to route the requests from the M sample buffers to one or more power calculation cores; the one or more power calculation cores, each configured to retrieve the samples from the sample buffer in an order of their corresponding priorities, in response to the routed requests, and to perform power calculation of the retrieved samples, wherein N and M are integers no less than 1, and N is no less than M. The present disclosure further provides a centralized power calculation method.

A computer-implemented method for combining static and dynamic code analysis may include 1) identifying executable code that is to be analyzed to determine whether the executable code is capable of leaking sensitive data, 2) performing a static analysis of the executable code to identify one or more objects which the executable code may use to transfer sensitive data, the static analysis being performed by analyzing the executable code without executing the executable code, 3) using a result of the static analysis to tune a dynamic analysis to track the one or more objects identified during the static analysis, and 4) performing the dynamic analysis by, while the executable code is being executed, tracking the one or more objects identified during the static analysis to determine whether the executable code leaks sensitive data via the one or more objects. Various other methods, systems, and computer-readable media are also disclosed.

A computer-implemented method may include maintaining a set of password-protection policies configured to prevent unauthorized access to a mobile device at different physical locations. The computer-implemented method may also include identifying a current physical location of the mobile device and searching a database that stores the set of password-protection policies for a particular password-protection policy that corresponds to the current physical location of the mobile device. The computer-implemented method may further include identifying, based on the search of the database, the particular password-protection policy that corresponds to the current physical location of the mobile device and then implementing the particular password-protection policy on the mobile device in response to the identification of the particular password-protection policy. Various other methods, systems, and computer-readable media are also disclosed.

A computer-implemented method for detecting malware may include 1) identifying an application configured to use a permission on a mobile computing platform, the permission enabling the application to access a feature of the mobile computing platform, 2) determining that the application is configured to use the permission while executing as a background application on the mobile computing platform, 3) determining that the use of the permission is suspect based on the application being configured to use the permission while executing as the background application, and 4) performing a remediation action in response to determining that the use of the permission is suspect. Various other methods, systems, and computer-readable media are also disclosed.
