Intel FPGA SDK for OpenCL Pro Edition Getting Started Guide The Inte/ FPGA SDK for OpenCL Pro Edition Getting Started Guide describes the procedures to install the Intel FPGA Software Development Kit (SDK) for OpenCL (1)Pro Edition This document also contains instructions on how to compile an example OpenCL(2)application with the Intel FPGA SDK for Open CL Pro Edition OpenCL is a C-based open standard for the parallel programming of heterogeneous devices. For more information about the openCL specification version 1.0, refer to the OpenCL 1.0 Reference Pages. For detailed information on the openCL application programming interface(APi)and programming language refer to the openCL Specification version 1.0 The intel FPGA SDK for OpenCl Pro edition provides a compiler and tools for you to build and run Open Cl applications that target intel FPGa products. The Intel FPGA SDK for OpenCL Pro Edition supports the embedded profile of the openCL Specification version 1.0 Attention: If you only require the Intel FPGA SDK for OpenCL's kernel deployment functionality download and install the Intel FPGa Runtime Environment(rte for OpenCL. Refer to the Inte/ fPGA RTE for OpenCL Pro Edition Getting Started Guide for more information Do not install the SDK and the rte on the same host system.

Prerequisites for the Intel FPGA SDK for OpenCL Pro Edition To install the Intel FPGA SDK for OpenCL Pro edition and create an OpenCl application for an Intel FPGA Preferred Board for OpenCL, your system must meet certain hardware target platform and software requirements Hardware Requirements Accelerator boards requirements Acquire a reference platform from Intel, or a custom Platform from an intel preferred board vendor. For more information refer to the intel FPGA sDK for OpencL FPGA Platforms page on the intel FPGa website. Development system requirements: You must have administrator root or sudo privileges on the development system to install the necessary packages and drivers The development system has at least 85 gigabytes(GB)of free disk space for software installation The development system has at least 24 GB of RAM Tip: Refer to board vendor's documentation on the recommended system storage sIze For PCI Express*(PCIe*) accelerator boards, the host machine motherboard must have an available pcle port slot that is at least the same width (that is, the same number of PCie lanes)as the board The host system must be running one of the following supported operating systems For a list of supported Windows and Linux operating systems refer to the Operating System Support page on the Intel FPGA website Software Prerequisites Develop your host application using one of the following Intel FPGA SDK for OpenCL and Intel Quartus Prime software-compatible C compiler or software development environment For Windows systems, use microsoft Visual studio professional and microsoft Visual c++ versions 2015 or later For Linux systems, use the C compiler included with the gCC. Linux systems require the perl command version 5 or later. Include the path to the Per command in your pAth system environment variable setting For Intel FPGa SDK for Open Cl packages that include Intel Code builder, intel code Builder requires java se version 1.8. 71 or later to run Related Information Intel FPGA SDK for Open CL FPGA Platforms □ Send Feedback Intel FPGA SDK for OpenCL Pro Edition Getting started Guid intel 1.Inte/ FPGA SDK for OpenCL Pro Edition Getting Started Guide UG-ocL001|2019.04.01 1.1.1. Intel FPGA SDK for OpenCL Pro Edition and BSP Backwards Compatibility The Intel FPGA SDK for OpenCL Pro edition Version 19. 1 compiler is compatible with board support packages(BSPs) from Version 19.1, Version 18.1, Version 18.0 and Intel Acceleration Stack Version 1.2. This backwards compatibility allows you to use older bsPs with newer compilers. However, some newer open cL compiler features might not be available to use with older BsPs To use an older Bsp with the Intel FPGA SDK for OpenCL, you must have a version of Intel Quartus Prime Pro Edition with the same version number as your BSP. For example, to use a Version 18.1 BSP with Intel FPGA SDK for OpenCL Pro Edition Version 19.1, you need Intel Quartus Prime Pro Edition Version 18.1 Related Information Enabling Backwards Compatibility for an FPGA Board on Windows on page 15 Enabling Backwards Compatibility for an FPGA Board on Linux on page 31 1.2. Contents of the Intel FPGA SDK for OpenCL Pro Edition The Intel FPGA SDK for openCl Pro edition provides programs, drivers, and SDK- specific libraries and files Logic Components The Intel FPGA SDk for OpenCL Offline Compiler translates your OpenCL device code into a hardware configuration file that the system loads onto an Intel FPGA product The Intel FPGA SDk for OpenCL Pro edition utility includes a set of commands you can invoke to perform high-level tasks such as running diagnostic tests The host runtime provides the OpenCL host and runtime aPi for your Opencl host applicatior The host runtime consists of libraries that provide openCL APIs, hardware abstractions, and helper libraries.
