Abstract: In the various aspects, virtualization techniques may be used to improve performance and reduce the amount of power consumed by selectively enabling a hypervisor operating on a computing device during sandbox sessions. In the various aspects, a high-level operating system may allocate memory such that its intermediate physical addresses are equal to the physical addresses. When the hypervisor is disabled, the hypervisor may suspend second stage translations from intermediate physical addresses to physical addresses. During a sandbox session, the hypervisor may be enabled and resume performing second stage translations.

Abstract: A wireless mobile device includes a graphic processing unit (GPU) that has a system memory management unit (MMU) for saving and restoring system MMU translation contexts. The system MMU is coupled to a memory and the GPU. The system MMU includes a set of hardware resources. The hardware resources may be context banks, with each of the context banks having a set of hardware registers. The system MMU also includes a hardware controller that is configured to restore a hardware resource associated with an access stream of content issued by an execution thread of the GPU. The associated hardware resource may be restored from the memory into a physical hardware resource when the hardware resource associated with the access stream of content is not stored within one of the hardware resources.

Abstract: Systems and methods are disclosed for providing memory address translation for a memory management system. One embodiment of such a system comprises a memory device and an application processor in communication via a system interconnect. The application processor comprises test code for testing one or more of a plurality of hardware devices. Each of the hardware devices has a corresponding system memory management unit (SMMU) for processing memory requests associated with the hardware device to the memory device. The system further comprises a client-side address translation system in communication with the system interconnect and the plurality of SMMUs. The client-side address translation system is configured to selectively route stimulus traffic associated with the test code to a client port on one or more of the plurality of SMMUs for testing the corresponding hardware devices.

Abstract: A system and method for evaluating programmable device systems captures, categorizes, indexes, manipulates and stores generated embedded trace generated information in an enterprise database. Use cases may be executed on an ETM enabled processor, ETM trace data may be captured, and captured trace data may be manipulated and stored in the enterprise database. The data collected from numerous use cases over multiple executions may be used to generate a differential comparison. The differential comparison may be used to interpret and predict bottlenecks, bugs and irregularities within the programmable device.

Abstract: A finite impulse response (FIR) filter employing hybrid coefficients for use in analog-to-digital and digital-to-analog conversion. Clock jitter introduced by the transmission medium may be compensated for by calculating an early interpolated data value and a late interpolated data value for each data point, and using the difference between the early and late interpolated values to produce a correction signal to the slicer clock in the converter. Hardware may be minimized by employing a hybrid coefficient in each filter tab which is reflective of the difference between an early and a late interpolated data value.
