Abstract:
A controller is described that includes wiring to transport notification that a FIFO that holds data to be used to display content on a display has reached a threshold. The controller also includes first control circuitry to turn on a phase locked loop (PLL) circuit to cause logic circuitry within the controller downstream from the PLL to begin to receive a first clock in response to the notification. The logic circuitry is to transport data read from a memory toward the FIFO. The controller also includes second control circuitry to cause the memory to use a second clock provided by the controller in response to the notification.
Abstract:
In accordance with some embodiments, a graphics process frame generation frame rate may be monitored in combination with a utilization or work load metric for the graphics process in order to allocate performance resources to the graphics process and in some cases, between the graphics process and a central processing unit.
Abstract:
Assertions of sentinel nodes within a device may be used to calculate device power consumption at runtime. These power estimates may be used to estimate a device temperature or leakage power, and/or may be used to make device throttling decisions.
Abstract:
Z testing during computer graphics rendering is performed in a manner so as to optimize rendering. The status of a pixel as non-promotable may be tracked using a pixel status array (PSA). Each PSA row may contain bits which correspond to the non-promotable status of pixels. Each row may include five pixels, the first four of which represent the pixels in a subspan. If the row corresponds to a valid subspan, a determination may be made as to whether any pixel in the subspan is represented by a one, indicating that the pixel is non-promotable. This row corresponds to a previous subspan that has been sent down rendering pipeline. If a one is present, then the current subspan may be stalled until the pixels of the previous subspan has gone through color calculation. If, in the row that has just been read, no pixels are represented by a one, then a determination may be made as to whether any pixels in the current subspan are non-promotable. If so, then the corresponding bit in the current PSA row may be set to one. Otherwise, the Z test may be performed on each pixel of the current subspan.
Abstract:
A method, apparatus and system for storing data wherein pieces of data are selectively combined at times when a storage device is not able to accept requests to store data for a duration sufficient that multiple additional pieces of data have been received since the last request to store data was made and at least two of those pieces of data are able to be combined into a piece of data that is better configured for storage.
Abstract:
Techniques to determine when to decrease a frame display rate based in part on the amount or degree of change between sequential frames. The amount or degree of change can be measured based on all or part of similarly located portions of sequential frames. In some cases, power use can be reduced without compromising visual quality by reducing frame display rate when an amount or degree of change between frames is small.
Abstract:
A system for addressing incompatibility between services and applications is disclosed. The system comprises an intermediation module, a mapper module and an execution module. The intermediation module is configured to receive a first call from an application and retrieve from a directory a reference to a service associated with the application. The mapper module is configured to retrieve, from the directory, service metadata describing the service and business metadata describing business on the application. The mapper module generates a mapping table that maps the business metadata to the service metadata for providing a response to the application query. The mapper module determines if an incompatibility exists between a business requirement associated with the application and the service. The execution module selects and executes an interface of the service based on the mapping of the business metadata and the service metadata.

Abstract:
A system and method for throttling a slave component of a computer system to reduce an overall temperature of the computing system upon receiving a first signal is disclosed. The first signal may be from a master component indicating that a temperature for the master component has exceeded its threshold temperature. The slave component or the master component may be a central processing unit, a graphics memory and controller hub, or a central processing unit memory controller hub. The slave component may send a second signal to indicate that a temperature for the slave component has exceeded its temperature. The master component would then initiate throttling of the master component to reduce the overall temperature of the computing system. The master component may be throttled to a degree less than the slave component. A first component may be designated the master component and the second component may be designated the slave component based on a selection policy. The selection policy may be received from a user through a graphical user interface. The selection policy may be based on an action being performed by the computing system.
Abstract:
A processor is provided with a workload that has a real-time demand. A processor clock frequency requirement is set for the processor, based on a deadline margin for the real-time demand. Other embodiments are also described and claimed.
