The present invention provides a motherboard that uses a high-speed, scalable system bus such as PCI Express® to support two or more high bandwidth graphics slots, each capable of supporting an off-the-shelf video controller. The lanes from the motherboard chipset may be directly routed to two or more graphics slots. For instance, the chipset may route (1) thirty-two lanes into two ×16 graphics slots; (2) twenty-four lanes into one ×16 graphics slot and one ×8 graphics slot (the ×8 slot using the same physical connector as a ×16 graphics slot but with only eight active lanes); or (3) sixteen lanes into two ×8 graphics slots (again, physically similar to a ×16 graphics slot but with only eight active lanes). Alternatively, a switch can convert sixteen lanes coming from the chipset root complex into two ×16 links that connect to two ×16 graphics slots. Each and every embodiment of the present invention is agnostic to a specific chipset.

The first processor elements are bidirectionally coupled to a first cache (12) via a crossbar switch matrix (8). The second processor element is coupled to a second cache (11). Each of the first cache and the second cache contain a two-way, set-associative cache memory that uses a least-recently-used (LRU) replacement algorithm and that operates with a use-as-fill mode to minimize a number of wait states said processor elements need experience before continuing execution after a cache-miss. An operation of each of the first processor elements and an operation of the second processor element are locked together during an execution of a single instruction read from the second cache. The instruction specifies, in a first portion that is coupled in common to each of the plurality of first processor elements, the operation of each of the plurality of first processor elements in parallel.

A method of generating graphic images on a display device of a computer system, by dividing the viewable area of the display device into a plurality of tiles, assigning each of the tiles to respective rendering processes, rendering a frame on the display device using the rendering processes, and adjusting the sizes of the tiles in response to the rendering step. The method then uses the adjusted tile sizes to render the next frame. The tile areas are preferably constrained from becoming too small. The adjusted tile sizes may optionally be smoothed, such as by averaging in weighted sizes from previous frames. The tile sizes are adjusted by measuring the rendering times required for each rendering process to complete a respective portion of the frame, and then resizing the tiles based on the measured rendering times.

A programmable, pipelined graphics processor (e.g., a vertex processor) having at least two processing pipelines, a graphics processing system including such a processor, and a pipelined graphics data processing method allowing parallel processing and also handling branching instructions and preventing conflicts among pipelines. Preferably, each pipeline processes data in accordance with a program including by executing branch instructions, and the processor is operable in any one of a parallel processing mode in which at least two data values to be processed in parallel in accordance with the same program are launched simultaneously into multiple pipelines, and a serialized mode in which only one pipeline at a time receives input data values to be processed in accordance with the program (and operation of each other pipeline is frozen). During parallel processing mode operation, mode control circuitry recognizes and resolves branch instructions to be executed (before processing of data in accordance with each branch instruction starts) and causes the processor to operate in the serialized mode when (and preferably only for as long as) necessary to prevent any conflict between the pipelines due to branching. In other embodiments, the processor is operable in any one of a parallel processing mode and a limited serialized mode in which operation of each of a sequence of pipelines (or pipeline sets) pauses for a limited number of clock cycles. The processor enters the limited serialized mode in response to detecting a conflict-causing instruction that could cause a conflict between resources shared by the pipelines during parallel processing mode operation.

A CPU module includes a host element configured to perform a high-level host-related task, and one or more data-generating processing elements configured to perform a data-generating task associated with the high-level host-related task. Each data-generating processing element includes logic configured to receive input data, and logic configured to process the input data to produce output data. The amount of output data is greater than an amount of input data, and the ratio of the amount of input data to the amount of output data defines a decompression ratio. In one implementation, the high-level host-related task performed by the host element pertains to a high-level graphics processing task, and the data-generating task pertains to the generation of geometry data (such as triangle vertices) for use within the high-level graphics processing task. The CPU module can transfer the output data to a GPU module via at least one locked set of a cache memory. The GPU retrieves the output data from the locked set, and periodically forwards a tail pointer to a cacheable location within the data-generating elements that informs the data-generating elements of its progress in retrieving the output data.

An apparatus, method, and system are described herein for providing programmable control of performance/event counters. An event counter is programmable to track different events, as well as to be checkpointed when speculative code regions are encountered. So when a speculative code region is aborted, the event counter is able to be restored to it pre-speculation value. Moreover, the difference between a cumulative event count of committed and uncommitted execution and the committed execution, represents an event count/contribution for uncommitted execution. From information on the uncommitted execution, hardware/software may be tuned to enhance future execution to avoid wasted execution cycles.

The control element controls the virtualization of the physical processors (CPs), the logical partitions (LPARs) and the logical processors (LCPs) and allocates the physical processor performances (PCPs) to the logical partitions (LPARs). The control element operates to exclusively bind logical processors (LCPs) to the physical processors (CPs). For a logical processor (LCP) exclusively bound to a physical processor (CP), the logical processor (LCP) has exclusive use of the underlying physical processor (CP) and no other logical processor (LCP) can be dispatched on the underlying physical processor (CP) even if the underlying physical processor (CP) is otherwise available.

Backlit LCD displays are becoming commonplace within many vehicle applications. The unique advantage of this invention is that it optimizes system power savings for display of low dynamic range (LDR) images by dynamically controlling spatially adjustable backlighting. This is accomplishes through use of a control technique that takes into account the sequential nature of the video display process.

A system and method for processing machine learning techniques (such as neural networks) and other non-graphics applications using a graphics processing unit (GPU) to accelerate and optimize the processing. The system and method transfers an architecture that can be used for a wide variety of machine learning techniques from the CPU to the GPU. The transfer of processing to the GPU is accomplished using several novel techniques that overcome the limitations and work well within the framework of the GPU architecture. With these limitations overcome, machine learning techniques are particularly well suited for processing on the GPU because the GPU is typically much more powerful than the typical CPU. Moreover, similar to graphics processing, processing of machine learning techniques involves problems with solving non-trivial solutions and large amounts of data.

The present invention relates to a parallel pipeline graphics system. The parallel pipeline graphics system includes a back-end configured to receive primitives and combinations of primitives (i.e., geometry) and process the geometry to produce values to place in a frame buffer for rendering on screen. Unlike prior single pipeline implementation, some embodiments use two or four parallel pipelines, though other configurations having 2^n pipelines may be used. When geometry data is sent to the back-end, it is divided up and provided to one of the parallel pipelines. Each pipeline is a component of a raster back-end, where the display screen is divided into tiles and a defined portion of the screen is sent through a pipeline that owns that portion of the screen's tiles. In one embodiment, each pipeline comprises a scan converter, a hierarchical-Z unit, a z buffer logic, a rasterizer, a shader, and a color buffer logic.
