Halide

Halide is a programming language designed to make it easier to write high-performance image and array processing code on modern machines. Halide currently targets:

CPU architectures: X86, ARM, MIPS, Hexagon, PowerPC
Operating systems: Linux, Windows, macOS, Android, iOS, Qualcomm QuRT
GPU Compute APIs: CUDA, OpenCL, OpenGL, OpenGL Compute Shaders, Apple Metal, Microsoft Direct X 12
Rather than being a standalone programming language, Halide is embedded in C++. This means you write C++ code that builds an in-memory representation of a Halide pipeline using Halide’s C++ API. You can then compile this representation to an object file, or JIT-compile it and run it in the same process.
