Huawei Ark compiler officially open source from GitHub for self-hosting
Recently, Huawei’s Ark compiler finally ushered in open source, and the open-source code is still carried on its own official website. Faced with such a compiler that shoulders the mission of “Beyond Android, better than Android”, it has received much attention since its inception; this open-source has attracted the attention of the public.
In order to build this “Ark”, Huawei has been grinding the sword for ten years.
In 2009, while Huawei launched the 5G basic technology research, it began to create a compilation group, and the first batch of researchers at home and abroad joined.
In 2013, Huawei launched the self-developed compiler HCC for the field of base stations, and formally proposed the compiler framework.
In 2014, many experts at home and abroad joined Huawei and the Ark project was officially launched.
In 2016, the Compiler and Programming Language Lab was established.
In 2019, the Huawei Ark compiler was officially launched.
According to Huawei’s official introduction, the Ark compiler is a unified programming platform designed to support the joint compilation and operation of multiple programming languages and multiple chip platforms, including key components such as compilers, tool chains, and runtimes. It is the first static compiler to completely replace a language virtual machine , and does not require an interpreter at all, while also taking into account Java development efficiency and C language efficiency.
Huawei claims that the Ark compiler can increase the smoothness of Android applications by up to 60%, improve the smoothness of mobile phone system operation by up to 24%, and improve system response performance by 44%.
According to Huawei’s experimental data, EMUI 9.1 only increased the system operation fluency by 24% and system response performance by 44% after applying the Huawei Ark compiler to the system component System Server. Sina Weibo Express Edition is the first third-party application to use the Ark compiler, and the operation fluency is increased by 60%.
“Out of Android, better than Android, beyond iOS, and fully compatible with Android” is the mission of the Ark compiler. At present, the Ark has been able to achieve “a unified intermediate representation of mixed languages and complete static compilation.” This is also its main two major advantages:
For the first time, the Ark compiler removed the virtual machine in the Java field. It is also the first time in the history of software to compile mixed code such as Java/C/C++ into machine code and run it directly on the mobile phone. It completely tells the Java JNI overhead and uses the memory recycling mechanism. Improve the smoothness of the operation.
The Ark compiler uses space for performance, so it can directly transfer the code of the compiler to the developer environment; so that developers are no longer limited by the hardware resources of the mobile terminal, providing unlimited possibilities for code optimization.
Huawei Sound X4 smart speaker was launched on Huawei Mall, and full pre-sale started on the same day, and the first sale of the new product started at 20:00 on October 31.
The smart speaker is available in two colors: Rhythmic Black and Dynamic White, priced at 2199 yuan and 2599 yuan respectively.
The speaker contains eight units, including 1 woofer, 4 mid-range speakers, 1 tweeter and 2 passive radiators . Officials said that the high, medium and low frequency units work within their respective frequency response ranges, giving full play to the advantages of each unit. A HUAWEI Sound X4 can bring “symphony orchestra-like” sound effects.
The speaker has obtained Hi-Res high-definition sound quality certification, which can provide more sound details and also perceive the spatial sense of the sound. Its subwoofer has a power of 50W and is also equipped with 2 passive radiators. The low frequency dives to 36Hz and has a 25mm stroke.
In addition, its high-frequency unit has a power of 3W and the mid-frequency unit has a power of 5W, and they use pure titanium diaphragm and self-developed mica fiber diaphragm respectively.
The speaker is equipped with Huawei SOUND bass enhancement algorithm, which can actively control the vibration of the speaker, reduce distortion, improve the transient response of low frequency, and achieve deep and powerful low frequency performance. It adopts Sym-Pole mirror design to offset vibration noise and bring rich bass.
In addition, it supports control methods such as one-touch, one-cover, and two-tap, which can respectively complete operations such as lighting, muting, and turning off the lights. The speaker also supports intelligent recognition of spatial structure, emitting sound waves to detect the room structure and receiving feedback, and can automatically match the sound effect scheme in the spatial scene.
Huawei’s GoPaint App was released in May this year and officially launched in August this year. The App is a digital painting software provided by Huawei. Yesterday, the app was newly adapted to 4 tablets including the MatePad Pro 11-inch 2022 model.
A user recently asked in the community for the app compatibility and support replied that “This function is expected to be supported in the first quarter of 2025.”
According to reports, the official version of GoPaint App has over 150 preset brushes, more than 80 brush parameters that can be adjusted, and fluid brushes that can restore the real pen-and-paper rendering effect. At the same time, new realistic canvas styles have been added, including watercolor, ink, oil painting, rock color, etc.
The official version of GoPaint App also has Fangtian Painting Engine 2.0 built in, supports 100+ 6K high-definition layers and 8K ultra-large canvas, and is the first to use a floating splash brush, which can splash ink by double-clicking the pen.
Huawei has now started rolling out the September 2024 security patch update to the Pura 70 lineup in Europe.
