摘要： A processor performance profiler is enabled to for identify specific instructions causing performance issues within a program being executed by a microprocessor through random sampling to find the worst-case offenders of a particular event type such as a cache miss or a branch mis-prediction. Tracking all instructions causing a particular event generates large data logs, creates performance penalties, and makes code analysis more difficult. However, by identifying and tracking the worst offenders within a random sample of events without having to hash all events results in smaller memory requirements for the performance profiler, lower performance impact while profiling, and decreased complexity to analyze the program to identify major performance issues, which, in turn, enables better optimization of the program in shorter developer time.

摘要： Primitives are divided into span groups of 2N spans, and then processed in M×N blocks of pixels, with the pixel blocks preferably being as close to square as possible and therefore optimized for small spans and texture mapping. Each span group is rendered block-by-block in a serpentine manner from an initial or entry block, first in a direction away from the long edge of the primitive and then in a direction towards the long edge. The interpolators include a one-deep stack onto which pixel and texel information for the initial or entry block are pushed before rendering any other blocks within the span group. Blocks or pairs of blocks within different span subgroups of the span group are then alternately rendered, such that rendering zig-zags between the span subgroups as it proceeds to the end of the span group. Once the first end of a span group is reached, the values for the initial or entry block are popped from the stack and rendering resumes from the initial or entry block in the opposite direction, but in the same serpentine or zig-zag manner, until the other end of the span group is reached. The next span group, if any, is rendered starting with a block adjacent to the last block rendered in the previous span group. Memory bandwidth utilization between the pixel and texel cache and the frame buffer is thus improved, together with texel reuse during texture mapping, to reduce the total number of pixel and texel fetches required to render the primitive.
摘要翻译： 原子被分成2N个跨度的跨度组，然后在M×N个像素块中进行处理，其中像素块优选尽可能接近正方形，因此针对小跨度和纹理映射进行优化。 每个跨度组以蛇形方式从初始或进入块逐块渲染，首先在远离原始长边的方向上，然后朝向长边的方向。 插值器包括一个深层堆叠，在渲染跨度组内的任何其他块之前，将初始或进入块的像素和纹素信息推送到其上。 然后交替地渲染跨度组的不同跨度子组内的块或块对，使得当它进行到跨度组的末尾时，在跨越子组之间渲染之字形。 一旦达到跨度组的第一个结束，初始或进入块的值从堆栈中弹出，并且渲染从初始或进入块以相反方向恢复，但是以相同的蛇形或锯齿形方式恢复，直到 到达跨度组的另一端。 下一个范围组（如果有的话）从与前一个范围组中呈现的最后一个块相邻的块开始绘制。 因此，像素和纹素高速缓存和帧缓冲器之间的存储器带宽利用率在纹理映射期间与纹素复用一起得到改善，以减少呈现原始图像所需的像素和纹素提取的总数。

摘要： Graphics information is efficiently transferred from a host computer to a graphics subsystem in which rendering and pixel data is generated by the host system. A masked span operation provides an assist for 3D rendering performed by the system processor of the host and other system resources. Storage of depth, alpha, stencil, and other pixel data is in system memory including one or more ancillary graphics buffers. The main processor of the host system generates pixel data associated with an image. This data is checked against the buffers. As a result of such checking, a mask is generated by the host system. The mask is transferred in burst mode across the host-graphic subsystem PCI bus to the graphics subsystem in combination with span width, and in the case of interpolated color, color base and color increment data, and X,Y coordinate of the first pixel. In the graphics subsystem the mask is employed with the other data to load the frame buffer with the portion of pixel data defined by the mask.

摘要： A pixel merge apparatus and method has been implemented. Included is a configurable graphics device, which may serve as a standalone graphics engine, or as a master or slave in a master/slave configuration. In stand alone mode, the mechanism drives a display device with native pixel data. A device configured in master mode is operable for receiving pixel data from a corresponding slave device, and merging the slave pixel data with native pixel data generated by a rasterizer within the ASIC. Data is communicated between slave and master using a digital data link which may also serve to drive a flat panel display in standalone mode. A FIFO, active in the master, mediates the transfer of the slave pixel data and permits switching between native and slave pixel data with signal pixel resolution. Pixel data may be merged on a frame-by-frame basis, or in split frame mode wherein a first portion of the graphic shown on a display device constitutes native pixels generated in the rasterizer corresponding to the master device, and a second portion of the displayed graphic includes pixels generated by the rasterizer in the slave device.

摘要： A system and method for identifying and manipulating logic analyzer data from multiple clock domains is presented. A logic analyzer receives debug data and determines whether the debug data is a full frequency data type, a half frequency data type, or a crossed data type. Once determined, the logic analyzer reconstructs the debug data such that debug condition-matching logic may process the reconstructed data in a full frequency domain. For half frequency data types, the logic analyzer adds masked data values to the data in order to reconstruct the data into to the full frequency domain before processing the data. For crossed data types, the logic analyzer reconstructs the data into its original format before processing the data in a full frequency domain.
