这是最近流行的opencl语言编写的hello world例程,运行成功
Hello World OpenCL Design Example README file ============================================= ============================================= This readme file for the Hello World OpenCL Design Example contains information about the design example package. For more examples, please visit the page: This file contains the following information: - Example Description - Software and Board Requirements - Usage Instructions - Package Contents and Directory Structure - Release History - Disclaimer & Licenses - Contacting Altera(R) Example Description =================== This example is a simple "hello world" kernel. It demonstrates: 1. An OpenCL accelerator kernel running on the FPGA that prints a message on the host system using a device-side printf. The thread which prints this message is controllable using a kernel argument set by the host program. 2. OpenCL queries of various platform and device parameters from within the host program. Software and Board Requirements =============================== This design example is for use with the following versions of the Altera Complete Design Suite and Quartus(R) II software and Altera SDK for OpenCL software: - 14.0 or later For host program compilation, the requirements are: - Linux: GNU Make and gcc - Windows: Microsoft Visual Studio 2010 The supported operating systems for this release: - All operating systems supported by the Altera SDK for OpenCL Usage Instructions ================== Linux: 1. make 2. ./bin/hello_world Windows: 1. Build the project in Visual Studio 2010. 2. Run (Ctrl+F5). AOCX selection -------------- The host program will use an AOCX file in the bin directory. If hello_world.aocx exists, then that will be used. Otherwise, the host program will examine the device name to extract the board name (which was passed as the --board argument to aoc) and check for a hello_world_<board>_140.aocx file. Package Contents and Directory Structure ======================================== /hello_world /device Contains OpenCL kernel source files (.cl) /host /src Contains host source (.cpp) files /bin Contains host binary and OpenCL binaries (.aocx) Generating Kernel ================= To compile the kernel, run: aoc device/ -o bin/hello_world.aocx --board <board> where <board> matches the board you have in your system. If you are unsure of the board name, use the following command to list available boards: aoc --list-boards This compilation command can also be used to target the emulator by adding the -march=emulator flag. If the board already has a AOCX file (see AOCX selection section above), be sure to either replace or relocate that AOCX file. Release History =============== SDK Version Example Version Comments ------------------------------------------------------------------------------- 14.0 1.2 Update documentation for 14.0 release. 13.1 1.1 On Linux, fix possible compilation issues in AOCL_Utils by including <unistd.h>. 13.1 1.0 First release of example Disclaimer & Licenses ===================== Copyright (C) 2013-2014 Altera Corporation, San Jose, California, USA.
