Abstract: A system including one or more input interface drivers, an input dispatcher, one or more applications, a system compositor and one or more output interface drivers. The input interface driver receives input events. The input dispatcher is modified to dispatch a current input event to a corresponding application after receiving an indication that a display image based upon a previous input event has been posted to an output interface driver. The corresponding application renders a new display image based upon the current input event. The system compositor posts the new display image to the output interface driver. The system compositor is also modified to send an indication to the input dispatcher that the new display image has been posted to the output interface driver. The system iteratively performs the process to latch the dispatching of input events to the display flip.

Abstract: A technique for efficiently compressing rendered three-dimensional images in a remote rendering system adds a novel render-assisted prediction function to an existing video compression framework, such as the standard H.264/5 framework. Auxiliary rendering information is separated from rendering information used to describe a reference image by a server system. A client system may alter the auxiliary data and generate a new image based on the reference image and rendered scene information from the auxiliary data without creating additional network bandwidth or server workload.

Abstract: Circuits, methods, and apparatus that inhibit the collection or updating of page characteristics where such information is not useful. One example inhibits the updating of page usage information for pages that are to be kept resident in memory and not swapped to disk. The pages for which page usage or other characteristic updates are to be suppressed can be identified in a number of ways, including using a set range of addresses, bits in page directory entries, bits in page table entries, one or more address registers, or one or more segments.

Abstract: Systems and methods for encoding a data word using an 8b/9b encoding scheme that eliminates two-aggressor crosstalk are disclosed. The 8b/9b encoding scheme enables a data word that can be subdivided into portions of eight bits or less to be encoded using code words having one extra bit than the corresponding portion of the data word. Each of the valid code words does not include any three consecutive bits having a logic level of logic-high (i.e., ‘1’), and represent transition vectors for consecutive symbols transmitted over the high speed parallel bus. An encoder and corresponding decoder are disclosed for implementing the 8b/9b encoding scheme. In one embodiment, the encoder/decoder implements a modified Fibonacci sequence algorithm. In another embodiment, the encoder/decoder implements a look-up table. In some embodiments, data words may be less than eight bits wide.

Abstract: Methods and apparatus for source operand collector caching. In one embodiment, a processor includes a register file that may be coupled to storage elements (i.e., an operand collector) that provide inputs to the datapath of the processor core for executing an instruction. In order to reduce bandwidth between the register file and the operand collector, operands may be cached and reused in subsequent instructions. A scheduling unit maintains a cache table for monitoring which register values are currently stored in the operand collector. The scheduling unit may also configure the operand collector to select the particular storage elements that are coupled to the inputs to the datapath for a given instruction.

Additionally, a threshold value is determined. Further, a single dimension of the low discrepancy sequence is selected. Further still, for each element included within the low discrepancy sequence, the selected single dimension is compared to the determined threshold value. Also, a subset of the low discrepancy sequence is generated, based on the comparing.

Abstract: One embodiment of the present invention sets forth a technique for performing aggregation operations across multiple threads that execute independently. Aggregation is specified as part of a barrier synchronization or barrier arrival instruction, where in addition to performing the barrier synchronization or arrival, the instruction aggregates (using reduction or scan operations) values supplied by each thread. When a thread executes the barrier aggregation instruction the thread contributes to a scan or reduction result, and waits to execute any more instructions until after all of the threads have executed the barrier aggregation instruction. A reduction result is communicated to each thread after all of the threads have executed the barrier aggregation instruction and a scan result is communicated to each thread as the barrier aggregation instruction is executed by the thread.
