Abstract: Aspects include computing devices, systems, and methods for dynamically partitioning a system cache by sets and ways into component caches. A system cache memory controller may manage the component caches and manage access to the component caches. The system cache memory controller may receive system cache access requests and reserve locations in the system cache corresponding to the component caches correlated with component cache identifiers of the requests. Reserving locations in the system cache may activate the locations in the system cache for use by a requesting client, and may also prevent other client from using the reserved locations in the system cache. Releasing the locations in the system cache may deactivate the locations in the system cache and allow other clients to use them. A client reserving locations in the system cache may change the amount of locations it has reserved within its component cache.

Abstract: Various embodiments of methods and systems for managing write transaction volume from a master component to a long term memory component in a system on a chip (“SoC”) are disclosed. Because power consumption and bus bandwidth are unnecessarily consumed when ephemeral data is written back to long term memory (such as a double data rate “DDR” memory) from a closely coupled memory component (such as a low level cache “LLC” memory) of a data generating master component, embodiments of the solutions seek to identify write transactions that contain ephemeral data and prevent the ephemeral data from being written to DDR.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. An apparatus determines whether a vision-altering object is present between the apparatus and at least one eye of a user. The apparatus identifies the vision-altering object as corresponding to a previously characterized object in response to determining that the vision-altering object is present between the device and the at least one eye of the user. The apparatus adjusts an image displayed at the apparatus based on one or more characteristics of the previously characterized object. Accordingly, the presence of the vision-altering object is compensated to allow the user to perceive an image that is closer to the image despite the presence of the vision-altering object.

Abstract: Techniques, apparatus and system for processing 3D graphics are provided. A graphics processor includes a fixed pipeline code generator to convert an application programming interface (API) supporting a fixed pipeline into first microcodes, a shader pipeline code generator to convert an API supporting a programmable pipeline into second microcodes, and a shader pipeline to process the first or second microcodes by using a shader program.
