20080276108 | METHOD AND SYSTEM FOR IMPLEMENTING GENERALIZED SYSTEM STUTTER - A method and system for implementing a generalized system stutter are disclosed. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of blocking a first request received from a first of a plurality of bus masters during a low power state of a computing device for as long as permissible by the timing requirements of the computing device, wherein the first request is capable of triggering the computing device to transition out of the low power state, and during an active state of the computing device, servicing the first request along with other pending requests from the rest of the plurality of bus masters before the computing device transitions back to the low power state. | 11-06-2008 |
20090083506 | Method and system for memory thermal load sharing using memory on die termination - Memory component temperature information is used to implement a method for ODT (on die termination) thermal load management. A respective temperature of a plurality of memory components are accessed, and based on this temperature, an ODT cycle is directed to a first of the memory components to avoid imposing a thermal load from the ODT cycle on a second of the memory components. | 03-26-2009 |
20090089477 | DEADLOCK AVOIDANCE IN A BUS FABRIC - Circuits, apparatus, and methods for avoiding deadlock conditions in a bus fabric. One exemplary embodiment provides an address decoder for determining whether a received posted request is a peer-to-peer request. If it is, the posted request is sent as a non-posted request. A limit on the number of pending non-posted requests is maintained and not exceed, such that deadlock is avoided. Another exemplary embodiment provides an arbiter that tracks a number of pending posted requests. When the number pending posted requests reaches a predetermined or programmable level, a Block Peer-to-Peer signal is sent to the arbiter's clients, again avoiding deadlock. | 04-02-2009 |
20090276597 | MEMORY CONTROLLER-ADAPTIVE 1T/2T TIMING CONTROL - Circuits, methods, and apparatus that adaptively control 1T and 2T timing for a memory controller interface. An embodiment of the present invention provides a first memory interface as well as an additional memory interface, each having a number of address and control lines. The address and control lines of the redundant memory interface may be individually enabled and disabled. If a line in the additional interface is enabled, it and its corresponding line in the first interface drive a reduced load and may operate at the higher 1T data rate. If a line in the additional interface is disabled, then its corresponding line in the first interface drives a higher load and may operate at the slower 2T data rate. In either case, the operating speed of the interface may also be considered in determining whether each line operates with 1T or 2T timing. | 11-05-2009 |
20100026692 | HYBRID GRAPHIC DISPLAY - A method of displaying graphics data is described. The method involves accessing the graphics data in a memory subsystem associated with one graphics subsystem. The graphics data is transmitted to a second graphics subsystem, where it is displayed on a monitor coupled to the second graphics subsystem. | 02-04-2010 |
20110109639 | POWER SAVINGS IN A COMPUTING DEVICE DURING VIDEO PLAYBACK - Display data and video data are stored within a graphics processing unit to reduce power consumed by the computing device during video playback. Storing display data and video data within the GPU reduces power consumption, because bus transaction activity is reduced and the need to read data from a larger, common main memory is avoided. | 05-12-2011 |
20110169845 | SCREEN COMPRESSION FOR MOBILE APPLICATIONS - One embodiment of the invention sets forth a technique for compressing and storing display data and optionally compressing and storing cursor data in a memory that is local to a graphics processing unit to reduce the power consumed by a mobile computing device when refreshing the screen. Compressing the display data and optionally the cursor data also reduces the relative cost of the invention by reducing the size of the local memory relative to the size that would be necessary if the display data were stored locally in uncompressed form. Thus, the invention may improve mobile computing device battery life, while keeping additional costs low. | 07-14-2011 |
20110173476 | USING NON-LOSSLESS COMPRESSION TO SAVE POWER - Circuits, methods, and systems that reduce or eliminate the number of data transfers between a system memory and a graphics processor under certain conditions. After inactivity by a user of an electronic device is detected, the color fidelity of pixels being displayed is reduced. Color fidelity can be reduced by compressing pixel values, and the compression may be non-lossless, for example, pixel data bits may be truncated. The degree of compression can be progressively increased for longer durations of inactivity, and this progression may be limited by a threshold. Inactivity may be detected by a lack of input from devices such as a keyboard, pen, mouse, or other input device. Once activity is resumed, uncompressed pixel data, or pixel data that is compressed in a lossless manner, is displayed. | 07-14-2011 |
