Abstract: In one embodiment, a processor may include a vector unit to perform operations on multiple data elements responsive to a single instruction, and a control unit coupled to the vector unit to provide the data elements to the vector unit, where the control unit is to enable an atomic vector operation to be performed on at least some of the data elements responsive to a first vector instruction to be executed under a first mask and a second vector instruction to be executed under a second mask. Other embodiments are described and claimed.

Abstract: Systems and methods to accelerate compression and decompression with a search unit implemented in the processor core. According to an embodiment, a search unit may be implemented to perform compression or decompression on an input stream of data. The search unit may use a look-up table to identify appropriate compression or decompression symbols. The look-up table may be populated with a table derived using the variable length coding symbols of a sequence of vertices to be compressed or extracted from a received data stream to be decompressed. A comparator and a finite state machine may be implemented in the search unit to facilitate traversal of the look-up table.

Abstract: A texture unit may be used to perform general purpose mathematical computations such as dot products. This enables some general purpose computations and operations to be offloaded from a central processing unit to the texture unit. The texture unit may use linear interpolators in order to perform the dot product calculations.

Abstract translation: 纹理单元可用于执行诸如点积的通用数学计算。 这使得一些通用计算和操作能够从中央处理单元卸载到纹理单元。 纹理单元可以使用线性内插器来执行点积计算。
