Advantages of the RISC-V architecture
Compared with the current mainstream Intel x86 architecture and ARM architecture, the RISC-V architecture has the advantages of simplified instructions, modularity, scalability, open source, and free. The RISC-V has only more than 40 basic instruction sets, plus dozens of other basic modular extension instructions, which is very simple, and any enterprise and developer can use the RISC-V instruction set for free, freely and without restriction to create IP cores or chips with completely independent intellectual property rights.
Especially in recent years, in the context of the United States continuing to increase restrictions on the development of other countries, more and more countries and manufacturers have begun to pay attention to the autonomy of chips, which has also promoted the accelerated development of the RISC-V ecosystem, which has now shown a three-legged trend with X86 and ARM.
According to Counterpoint Research, the number of chips using the RISC-V architecture will grow to 80 billion by 2025, and RISC-V will account for 14% of the global CPU market, 28% of the IoT market, 12% of the industrial market and 10% of the automotive market.
In order to meet the needs of users for remote control, industrial control and other RF solutions such as independent control, small size, and low cost, SI24R03 and SI24R04 were launched. SI24R03 SI24R04 is based on 24GHz band wirelessSend and receiveSingle launch+risc-v rv32imac kernel (2.)6 CoreMark MHz) 32-bit low-power, low-cost MCU chip, up to 32MHz, up to 32KB embedded flash, 4KB SRAM and 4.5KB NVM, integrated 13, 14, 15, 16-bit high-precision ADC and UART, I2C, SPI and other general peripheral interfaces.
