clearer. Figure 1 Cpu-gpu heterogeneous computing advocated by the OPENCL standardWe know that CPUs and GPUs have strengths, and the CPU is generally adept at handling irregular data structures and unpredictable access patterns, as well as recursive algorithms, branch-intensive code, and single-threaded threads. Such program tasks have complex instruction scheduling, looping, branching, logical judgments, and execution steps. For example, system so

industry-standard OpenGL and OpenAL, which are used for three-dimensional graphics and computer audio, respectively, for the two standard. OpenCL extends the ability of the GPU to be used outside of graphics generation. OpenCL is run by Khronos Group, a nonprofit technology organization. In addition, OpenCL is a cross-platform standard and not a cross-platform t

Xilinx, Inc. (NASDAQ:XLNX), the world leader in Programmable technology and devices, announced today the launch of OpenCL, C and c+ at the 2014 International Super Computing 2014 + SDACCELTM development environment, increase unit power performance by up to 25 times times, thereby using FPGA to achieve Data Center application acceleration. SDAccel is the newest member of the Xilinx SDX series, combining the industry's first architecture-optimized compi

example: In a pair of images, you can perform a filtering operation on the pixels in a sliding window (for example, 3*3 pixels) to obtain the convolution of an output pixel. Multiply the row I of the first input matrix by column J of the second input matrix. The obtained vector and element of column J of the row I of the output matrix are obtained. This method is effective for one-to-one or multiple-to-one mappings between input and output data. Some data decomposition algorithms are based

Recently, khronos announced the first test version of opencl (Open Computing language). Once released, it was a big wave in the field of general computing! Opencl is an open and free standard for concurrent programming for general purposes of heterogeneous systems, initiated by Apple and jointly developed by many famous manufacturers in the industry. It is also a unified programming environment. It facilita

Since Apple officially submitted its opencl to the khronos group Open Standards Organization in, it has received support from major companies such as AMD, NVIDIA, and Intel. Opencl can make full use of GPU data-intensive large-scale computing capabilities, so that many multimedia applications and even scientific computing can greatly improve performance. Here we
