Abstract: A method of statically allocating memory for a computer program includes splitting a computational graph associated with a plurality of static memory allocation constraints into a plurality of subgraphs; determining a memory allocation for each combination of subgraphs of the plurality of subgraphs using an SAT solver and a plurality of Boolean conditions that formalize the plurality of static memory allocation constraints; subdividing a subgraph of the plurality of subgraphs into a plurality of tiles, when the memory allocation for that subgraph cannot satisfy a hardware memory size constraint of the plurality of static memory allocation constraints; performing a performance analysis on all possible subgraphs and plurality of tiles; selecting a combination of subgraphs whose plurality of tiles has a best overall performance; and determining a memory allocation for the plurality of tiles for the selected combination of subgraphs using the SAT solver.

Abstract: Systems and techniques of the present disclosure enable a compiler to optimize such tradeoffs, and further enable optimization for a specific user cost function (e.g., optimization of a complex multi-dimensional and non-linear problem). Moreover, the techniques described herein can optimize in polynomial time. Accordingly, inference tasks may be optimized (e.g., based on specific applications) in terms of power consumption, idle time, the efficiency of computation, system resources, etc. For instance, by leveraging the systems and techniques described in the present disclosure, hardware designers can balance the tradeoff between runtime, power consumption, and resource usage, which are critical factors in the efficient processing of specialized tasks.

Abstract: A method includes, in a processor (44) of a user device (24), preloading one or more user applications (26) in a background mode, in which activities associated with preloaded user applications are hidden from a user of the user device. An activity, which is invoked in the processor and is associated with a given preloaded user application, is detected. An assessment is made by the processor, whether the activity is a preload-initiated activity that is invoked due to preloading of the given user application, or whether the activity is a user-initiated activity that is invoked due to an action by the user. If the activity is assessed to be a preload-initiated activity, the activity is handled using a first handling scheme. If the activity is assessed to be a user-initiated activity, the activity is handled using a second handling scheme, different from the first handling scheme.

Abstract: A user device includes a memory and one or more processors. The memory is configured to store one or more user applications installed in the user device.

The one or more processors are configured to pre-load a user application by running at least part of a program code of the user application in a background, including enabling the program code of the user application to pre-render a visual display of the user application in the background, and, in response to the user accessing the user application, to transfer the pre-rendered visual display to a foreground, thereby displaying the visual display to the user on the display screen.

Abstract: A user device (24) includes a display (56), audio circuitry (58) and a processor (44). The processor is configured to run an application that includes visual content and audio content, by: (i) before a user of the user device invokes the application, running the application in a background mode in which the visual content is not visible on the display, and inhibiting the audio content from being played by the audio circuitry, and (ii) after the user invokes the application, switching to run the application in a foreground mode in which the visual content is visible on the display, and permitting the audio content to be played by the audio circuitry.

The one or more processors are configured to receive from a user of a user device a request to access a User-Interface (UI) unit that includes one or more content items, to initially display, in response to the request, the UI unit to the user with versions of the content items that are available for immediate display in the user device, regardless of whether the initially displayed versions are up-to-date or not, and, for at least a content item whose initially displayed version is not up-to-date, to obtain an up-to-date version of the content item, and merge the up-to-date version of the content item transparently to the user into the UI unit being displayed, to replace the initially displayed version.

The network interface is configured for communicating over a communication network (32).

Abstract: A method for content delivery includes selecting one or more time intervals. During each time interval among the selected time intervals, given content is prefetched from a content source to a communication terminal using a guaranteed prefetching mode, by continuously tracking the given content on the content source, so as to detect changes to the given content as they occur during the selected time interval, and maintaining the communication terminal continuously synchronized with the content source with respect to the given content, throughout the selected time interval, notwithstanding the changes that occur during the selected time interval, by continuously prefetching at least part of the given content from the content source to the communication terminal. Outside of the one or more selected time intervals, the given content is prefetched using a best-effort prefetching mode, by tracking the given content less frequently than the guaranteed prefetching mode.
