What is OpenCL FPGA?

Overview. Intel® FPGA SDK for OpenCL™ software technology1 is a world class development environment that enables software developers to accelerate their applications by targeting heterogeneous platforms with Intel CPUs and FPGAs.

Can OpenCL be used with any FPGA?

OpenCL kernel code is essentially C code. Altera’s yet-to-be-named tool will convert the OpenCL code into logic that can be programmed into the FPGA. Initially this programming will be a static process and multiple OpenCL kernels could be handled by a single FPGA.

What is Intel FPGA SDK for OpenCL?

The Intel FPGA SDK for OpenCL is an OpenCL-based heterogeneous parallel programming environment for Intel FPGAs. This guide describes the hardware and software design of the Cyclone V SoC Development Kit Reference Platform (c5soc) for use with the Intel FPGA SDK for OpenCL.

How do I start OpenCL?

The main steps of a host program is as follows:

1. Get information about the platform and the devices available on the computer (line 42)
2. Select devices to use in execution (line 43)
3. Create an OpenCL context (line 47)
4. Create a command queue (line 50)
5. Create memory buffer objects(line 53-58)

What is the first step in developing a design with OpenCL?

When writing an OpenCL program for an FPGA, emulation is a crucial first step that allows us to efficiently debug OpenCL code.

What can I do with FPGA?

FPGAs are particularly useful for prototyping application-specific integrated circuits (ASICs) or processors. An FPGA can be reprogrammed until the ASIC or processor design is final and bug-free and the actual manufacturing of the final ASIC begins. Intel itself uses FPGAs to prototype new chips.

What is Windows OpenCL?

OpenCL™ (Open Computing Language) is a low-level API for heterogeneous computing that runs on CUDA-powered GPUs. In addition to OpenCL, NVIDIA supports a variety of GPU-accelerated libraries and high-level programming solutions that enable developers to get started quickly with GPU Computing.

Is FPGA difficult?

FPGA vendors have touted their wares as ideal replacements for DSPs, CPUs, and GPUs – even for all of them in a single device – but they are notoriously difficult for software engineers to program as they are not anything like a conventional processor.

What does OpenCL mean for a FPGA SDK?

OpenCL™ is a standard for writing parallel programs for heterogeneous systems. With the Intel® FPGA SDK for OpenCL, OpenCL constructs are synthesized into custom logic for optimal acceleration on FPGA devices. This course introduces the basic concepts of parallel computing.

Is there an Intel FPGA runtime environment for OpenCL?

Before using the Intel® FPGA SDK for OpenCL™ or the Intel® FPGA Runtime Environment (RTE) for OpenCL to program your device, familiarize yourself with the respective getting started guides. This document assumes that you have performed the following tasks:

What kind of programming model does OpenCL use?

OpenCL™ standard is a programming model for software engineers and a methodology for system architects. It is based on standard ANSI C (C99) with extensions to extract parallelism.

Where do I find the OpenCL source file?

An OpenCL kernel source file ( .cl) contains your OpenCL kernel source code that runs on the FPGA. The offline compiler groups one or more kernels into a temporary file and then compiles this file to generate the following files and folders:
