    Exactly two years ago, on such days, with the issuance of an executive order by the former US President and the inclusion of Huawei and its affiliates in the Entity List of China, the company was banned from purchasing US services and equipment without the approval of the central government. The restriction, which first had an impact on software and led by Google services, entered a new phase on its anniversary in mid-May last year, when foreign chip companies joined in and banned Huawei. TSMC, the largest independent processor manufacturer, has lost the ability to work with HiSilicon, a subsidiary of Huawei processor designers.

    It has not been idle for two years, and apart from accelerating its efforts to replace Google services with HMS or Huawei mobile services and expand the AppGallery software store, it has also taken extensive measures in the hardware sector. One of the first steps in this direction was the gradual transfer of Huawei chips from the Taiwanese company TSMC to the Chinese company SMIC, which, of course, due to the older technology of the company, included only the lower level chips needed for low-cost handsets. Last year, the Chinese government announced a $ 2.25 billion investment in SMIC to supply Huawei chipsets.

    Thus, it goes without saying that Huawei is looking for ways out of this crisis in both the hardware and software sectors, which, by relying on internal resources, minimizes the risk of losing opportunities by adopting foreign technologies. . Huawei has announced the production of the first RISC-V board for developers of the Harmoney OS platform, which has an open source architecture.

    Huawei's new board is called HiSilicon Hi3861, which is based on the Hi3861 controller of this company, and although in the manufacturer's description to The exact function of this chip is not mentioned, but it is referred to as the main controller chip. Comes with a serial port controller and a USB-C port. This board apparently has all the logic circuits needed to operate the USB-C port, and in situations like the Raspberry Pi, a wide range of functions can be considered for it. These capabilities, of course, are far from the core performance of Huawei's HiSilicon suite, but it can be considered the first solid step to overcome the current difficult situation.

    while target The key to building the Hi3861 is gaining access to the vast IoT market, with the HiSilicon suite focusing on CPUs for devices such as smartphones, tablets, and computers. On the other hand, it goes without saying that apart from areas such as mobile phones, Huawei also needs other computing platforms for its other products, and examples like HiSilicon Hi3861 will be able to meet this need.
