As the "brain" of intelligent devices, MCU (microprocessor) is a chip that integrates CPU, memory, peripheral interface and other functions. The advent of the aiot era has posed many new challenges to chip design, such as customization, rapid iteration, scalability and compatibility. The traditional chip architecture can not be fully met, and the simple and flexible risc-v architecture has become the first choice of many head manufacturers, driving the wave of independent research and development of MCU.
Apter is one of the best. Apt has been deeply engaged in MCU for nearly 10 years, with more than 100million PCs shipped in 2021. It is the largest MCU enterprise producing 32-bit processors in China. Relying on pingtouge xuantie processor, apt has built a full set of MCU IP library. Its MCU is widely used in Midea, Xiaomi, Panasonic, Bosch and other brand products, and has achieved a 100 million scale commercial landing verification in the fields of home appliances, wearable electronics, health and so on.
"According to the market demand, only by truly customizing the chip can we achieve innovation transcendence. The flat head Ge xuantie processor covers all computing power gears, has been iterated for a long time and has been verified by the large-scale market, and provides a sword free 100 SoC design platform and system software tools, which provides a good foundation for our independent research and development of chips." Yuan Yongsheng, deputy general manager of apt, said, for example, in the field of variable frequency microwave ovens, apt and Flathead worked together to optimize the processor architecture according to customer needs, and the limit of MCU product R & D and design cycle was shortened to 4 months. "Traditional chip architecture cannot achieve such agile development."
It is reported that pingtouge and apt will jointly develop and launch six risc-v chip series in the future, including voice AI MCU, automobile MCU, etc. Among them, automobile MCU is the core device for the development of intelligent driving industry. A car needs dozens to hundreds of MCU, which is regarded as the next key track of MCU.
"The close cooperation between apt and Flathead proves the development potential of risc-v in the field of diversity chips." Meng Jianyi, vice president of Flathead, said, "in order to promote the goal of Pratt Whitney computing power, Flathead will continue to break through the core technology of risc-v, continuously reduce the threshold of chip design, give customers customization ability, ensure high stability, and promote risc-v to achieve more distinctive innovative development."
Previously, xuantie risc-v won the first place in the four mlperf items of the world's authoritative AI benchmark, refreshing the upper limit of performance; Xuantie c910 took the lead in realizing the AI support of the new version of Android 12.0 and constantly expanding the ecological boundary; The four commercial processors and series of software and tools of xuantie have also been opened to the public. Up to now, more than 200 enterprises, including Ziguang zhanrui, Quanzhi technology, Hangzhou Guoxin, Zhuhai Juxin, Zhixin micro, Zhuosheng microelectronics, apt, Zhongke Lanxun, Jingshi, boliu, nastar, are designing chips based on xuantie processors.
