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, 5.0, and 5.1 for GPU offload†
- Trusted Technology: Uses well-proven LLVM compiler technology as well as Intel's history of compiler leadership
†Available in the Intel oneAPI DPC++/C++ Compiler only.
FPGA Emulation and Compilation
- Enables experienced FPGA developers to target accelerations workloads to field-programmable platforms
- Is included with the compiler
Note Full FPGA programming requires the optional Intel® FPGA Add-on for the oneAPI Base Toolkit.
