Features
Cross-Architecture Compiling
- Development Productivity: Targets CPUs and accelerators through single-source code while permitting custom tuning
- Language Standards Support: Is built to the latest standards, including C++ 17 and SYCL†, and initial support for C++ 20, to ensure portability and support of features like generic lambda expressions and variable templates
- Industry Standards Support: Supports a subset of OpenMP* 4.5 and 5.0 for GPU offload†
- Trusted Technology: Leverages well-proven LLVM compiler technology as well as Intel’s history of compiler leadership
†Available in Intel oneAPI DPC++/C++ Compiler only.
FPGA Emulation and Compilation
- Enables experienced FPGA developers to target accelerations workloads to field-programmable platforms
- Is an optional add-on to the Intel oneAPI Base Toolkit
Note Full FPGA programming requires the optional Intel® FPGA Add-on for oneAPI Base Toolkit.
