For job requirements, the two high-level language synthesis tools were applied, and the typical algorithms were implemented and evaluated (data is temporarily kept secret).Briefly talk about the experience of using.1. Altera OpenCL SDKFirst, you need to install Quartus (more than 13.1 version) and the supporting Soc EDS, respectively, apply for two license, one for the OpenCL SDK, one for soceds, indispensa

scratch register will tell you which interrupt was generated by the drawing command.The fence interrupt handler function is radeon_fence_poll_locked. First read the fence number, know that the fence operation caused the interruption, when the resulting interrupt fence number is the last number, you need to assign the last fence number to the current number, while updating the fence timer. If the interrupt is not the last fence number, the timer needs to be judged and then the fence interrupt qu

Here we will introduce how to write the program function in opencl. The program function is usually in the text format and load it in using interfaces such as clcreateprogramwithsource. This type of code is often used in shader programming to write the code running on the GPU. So for clarity and understanding, let's call the source code text of these program functions as the shader of opencl. The following

Nvidia's graphics card first to download the installation Cuda development package, you can refer to the steps here: VS2015 in the build environment Cuda installation configuration After the installation of Cuda, the configuration of OpenCL has been completed 80%, the rest of the work is to add the OpenCL path to the project. 1. Create a new Win32 Console application, add a property page "Opencl.props" in

1. Expand the Cycle If you know the number of cycles in advance, you can do cyclic expansion, which eliminates the number of times the cycle conditions are compared. But it also doesn't make kernel code too big. Looping through code examples: #include 2. Avoid dealing with non-standardized figures OpenCL numbers are normal values that are less than the minimum exponent. Because of the limited number of digits in the computer, the range and prec

Prior to the NVIDIA Cuda multi-card, under Linux with Pthread control, but OpenCL to do the initialization too much, although similar, but still encountered some problems. There is a multi-card sample program under ATI OpenCL driver, but I'm still used to following my own ideas. First build a structure device, including context, Commandqueue, program, kernel and other variables, each card corresponds to a

Accelerating computer vision algorithms using opencl on the mobile GPU March 12th, 2013 Abstract: Recently, general-purpose computing on graphics processing units (gpgpu) has been enabled on mobile devices thanks to the emerging heterogeneous programming models such as opencl. the capability of gpgpu on mobile devices opens a new era for mobile computing and can enable computationally demaning computer vi

Reference Link: https://www.jianshu.com/p/ad808584ce26Installing OpenCLOpenCL is a series of libraries and header files that need to be installed according to the hardware of the SDK, that is, if you want to use Intel CPU as a parallel device, you must install the Intel SDK, if you use the NVIDIA GPU as a parallel device, you must install the Nvidia SDK. Here are the configuration methods for running OpenCL on Intel CPUs and Nvidia GPUs, which can be

At hand a RK3288 board, on the board tested a 1080p color graph gray Conversion of OpenCL example. OpenCL does not have any optimizations. For example, please visit here. This example is an executable program compiled under the cheer Android platform.Go to the Jni folder and do the following:For my environment, the executable files, kernel.cl, and pictures are push to the//mnt/sdcard/

Complex algorithms are not necessarily inefficient, and simple algorithms often pay a price, which can be costly. Programming in the OPENCL environment has some differences with our traditional programming ideas on the CPU, which seem trivial, but often the details determine success, and these seemingly insignificant differences are infinitely magnified on multicore GPUs, resulting in a huge difference in the performance of the same algorithm on the G

These days, looking at the OpenCL Programming Guide, follow the example in the book to implement the Sobel algorithm:1. Combine OpenCV to read the image and save to the buffer;2.

Change chapter friends in Shanghai shopping when suddenly thought of ... There were a few notes about memory execution, so I went home to write it my dissertation. Farewell attention, reprint quote please specify http://blog.csdn.net/leonwei/article/details/8909897 This will further illustrate some of the features of the OpenCL API 1. Create buffer The operation that touches memory and graphics is always complicated, and this function is the same

The main reason is that the teacher used different methods to calculate the natural logarithm and understand the characteristics of different parallel languages. So I used multithreading. After OpenMP, I want to use opencl to implement the following. First I will introduce the algorithm. Method 1. Code host /* Project: multiply the matrix of opencl by: Liu Rong time: 2012.11.20 */# include Kernel Functio

In this tutorial, we will learn how to use opencl for simple image processing and rotating an image. Image reading, saving and other work, we use open source freeimage,: http://freeimage.sourceforge.net/ First, we create a gfreeimage class to load images. This class mainly calls the freeimage function, first initializes the freeimage library, and then guesses the image file format based on the file name, load the image file to the variable fibitmap *

Now we use the method in the previous tutorial to count the number of pixels in a pair of rgba images (This pixel satisfies the arbitrary components of R, G, B, And a> = 5 )? The method I want to consider is to create a histogram of 256 bin. For a pixel, calculate max (R, G, B, A) and use this value to determine the pixel to enter the bin, after obtaining the histogram, the width * Height-hostbin [0]-hostbin [1]-hostbin [2]-hostbin [3]-hostbin [4], that is, the result we want.
