ArkCompiler

A unified programming platform developed by Huawei that allows high-level languages to be compiled and executed across multiple chip platforms, thanks to its compiler, toolchain, runtime, and other powerful components. It enables apps and atomic services to run on a wide range of devices, such as smartphones, PCs, tablets, TVs, telematics devices, and wearables.

AOT compilation mode

ArkCompiler uses the static type information of ArkTS to perform type inference and generate object descriptions and inline caches, accelerating bytecode interpretation and execution at runtime. The AOT Compiler uses the static type information and profiling information to compile bytecode into optimized machine code. This ensures that high-performance code is executed at app startup, enhancing both startup and runtime performance.

LiteActor lightweight concurrency

ArkCompiler provides TaskPool and Worker APIs on HarmonyOS to enable concurrent programming. It optimizes startup performance and memory overhead during concurrent execution by isolating instance memory at runtime, and sharing immutable objects, built-in code blocks, and method bytecode from the running instances.
