Ark Compiler, also known as ArkCompiler, is a unified compilation and runtime platform that supports joint compilation and running across programming languages and chip platforms, also operating systems of open-source OpenHarmony, Oniro OS, alongside proprietary HarmonyOS with single core system HarmonyOS NEXT included on native APP in Event-driven programming in a unified development environment and formerly built for Android-based EMUI for Huawei smartphones and tablets with HMS-enabled apk apps on AppGallery that improves app performance. [2] It supports a variety of dynamic and static programming languages such as JS, TS, and ArkTS. It is the compilation and runtime base that enables OpenHarmony, Oniro OS alongside HarmonyOS NEXT to run on multiple device forms such as smart devices, mobile phones, PCs, tablets, TVs, automobiles, and wearables. ArkCompiler consists of two parts, compiler toolchain and runtime. [3]

Huawei initially open sourced Ark Compiler for Android platform on GitHub, on September 9, 2019, as they were transitioning away from the operating system via US sanctions. [4] Then the company, open sourced Ark Compiler with OpenArkCompiler as part of the Huawei Ark Compiler open source project (HACOSP) in early February 2022 [5] and ArkJS_runtime, in the previous year in September 2021 after two years of inception in August 2019. [6]

Overview

ArkCompiler has a built-in componentized and configurable multi-language compilation and runtime platform of OpenHarmony and HarmonyOS with HarmonyOS NEXT. It contains the core components such as the compiler, toolchain, and runtime. It supports compilation and running of high-level programming languages on the multi-chip platform. ArkCompiler JS Runtime provides the capability of compiling and running the JavaScript (JS) language on the OpenHarmony operating system side.

ArkCompiler JS Runtime consists of two parts such as the JS compiler toolchain and JS runtime. The JS compiler toolchain compiles JS source code into ArkCompiler bytecodes. The JS runtime executes the generated ArkCompiler bytecodes. [7]

The common module of language runtime in OpenHarmony operating system called ArkCompiler Runtime Core also created as Ark Runtime on top of HarmonyOS Runtime base on current dual-framework, alongside single framework OpenHarmony-based HarmonyOS NEXT which consists of language-independent basic runtime libraries, including ArkCompiler File, Tooling, Base and ISA. The ArkCompiler File provides bytecodes and information required for executing the bytecodes. Tooling supports the runtime debugger. The Base is responsible for implementing platform related utilities. ISA function provides common instruction set architecture that is language-independent that allows to run HarmonyOS applications regardless of different instruction set and chipsets in hardware with great compatibility of diverse set of hardware and interoperability between HarmonyOS, Oniro and OpenHarmony software and hardware ecosystems. [10]

ArkCompiler JS Runtime

ArkCompiler JS Runtime is the default JS runtime on OpenHarmony. It supports ECMAScript libraries and efficient container libraries. It also provides a set of native APIs for C++ and JS interaction and a variety of garbage collectors that features high performance. [11]

Ark TypeScript Runtime

ARK TypeScript Runtime is a runtime used in ArkTS applications derived from former HarmonyOS 3.0/OpenHarmony 3.1 API 8 eTS (extendedTypeScript) on OpenHarmony as well as HarmonyOS apps taking advantage of custom OpenHarmony-based HarmonyOS NEXT core operating system. It contains an allocator and garbage collector (GC) for ArkTS/JS objects, a standard library that conforms to the ECMAScript specification, an interpreter for running the ARK Bytecode (abc) generated by ARK front-end components, an inline cache for acceleration, a statically typed compiler, a C++/C function interface for Native API (NAPI) application development at runtime, and other modules in Ahead-of-time compilation via DevEco Studio since version 3.1.1 on both HarmonyOS 3.1 SDK and OpenHarmony 3.2 SDK API 9. [12]

ets_frontend

The ets_frontend is a front-end tool in the ARK Runtime Subsystem which combines the ace-ets2bundle component that supports converting ETS programming language files into ARK bytecode files. They correspond with ArkTS app development in OpenHarmony and HarmonyOS development under HarmonyOS NEXT system. [13]

ArkCompiler Toolchain

The ArkCompiler Toolchain provides developers with debugging tools for ArkTS application development, such as the Debugger, CPUProfiler, and HeapProfiler. The debugging and tuning capabilities provided by the Ark Toolchain is used through DevEco Studio IDE that relies on the ArkCompiler Runtime to provide runtime-related information to developers. [14]

A computing platform, digital platform, or software platform is an environment in which software is executed. It may be the hardware or the operating system (OS), a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed using the services provided by the platform. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.
