WebImplement the SAXPY routine in OpenCL. SAXPY can be called the "Hello World" of OpenCL. In the simplest terms, the first OpenCL sample shall compute A = alpha*B + C, where alpha is a constant and A, B, and C are vectors of an arbitrary size n. In linear algebra terms, this operation is called SAXPY ( Single precision real Alpha X plus Y ). WebCo-written with Hongqiang Wang and Alex Bourd Our previous post about OpenCL optimization on the Qualcomm® Adreno™ GPU described several candidate use cases. In this post we’ll cover a two-step optimization for apps that use the Sobel filter. The optimization is based on data load improvement, OpenCL functions, and support for … small coke bottle price
