RISC-V is an open source instruction set architecture (ISA) based on the principle of Reduced Instruction Set (RISC). Compared to most instruction sets, the RISC-V instruction set can be freely used for any purpose, allowing anyone to design, manufacture, and sell RISC-V chips and software. The design of the RISC-V instruction set takes into account the reality of being small, fast, and low-power, but does not overly design specific microarchitectures.
China Mobile Internet of Things Co., Ltd. is a wholly-owned subsidiary invested and established by China Mobile Communications Group Co., Ltd. According to the overall strategic layout of China Mobile, the company focuses on the strategic positioning of "a supporter of IoT business services, a provider of specialized modules and chips, and a promoter of IoT specialized products", specializes in operating IoT specialized networks, designing and producing IoT specialized modules and chips. Currently, it has successfully completed safety MCU, mainstream MCU, and ultra-low power MCU. Focusing on 5G+IOT, we will continue to explore and research cutting-edge IoT technologies, accumulate core capabilities, create high-quality products and services, empower the digital transformation of Qianxing Baiye, promote the digital and intelligent development of society, and enrich people's beautiful life experience of the Internet of Things.
