We currently use more architectures: ARM, RISC-V, MIPS, X86 and so on. In fact, there are some instructions, but other instructions are relatively small and only used in professional fields.
ARM architecture is a 32-bit reduced instruction set processor architecture, which is widely used in many embedded system designs. It is mainly engaged in the research and development of low-cost, low-power, high-performance chips, so the ARM processor is very suitable for the mobile communication field, so 99% of the world's smart phones and tablet computers use the ARM architecture. The ARM family accounts for 75% of all 32-bit embedded processors, making it one of the largest 32-bit architectures in the world. ARM is mainly geared towards mobile and low-power consumption, so it emphasizes energy saving and energy efficiency in design.
X86 mainly faces the computer industry. It is a computer language instruction set executed by a microprocessor, which refers to the standard number abbreviation of an intel general-purpose computer series, and also identifies a set of general computer instruction sets. On June 8, 1978, the x86 architecture was born. Its CPU is basically above 1G, dual-core and quad-core are popular, usually using 45nm or more advanced process technology for production. The X86 computer uses a "bridge" method to connect to the expansion device, so the computer can be more easily expanded.
The RiSC-V architecture is an open instruction set architecture based on the simplified instruction set calculation principle. It is a brand new instruction established on the basis of the continuous development and maturity of the instruction set. This instruction set will not be monopolized or profitable. It has a simple architecture and is completely open source, allowing anyone to design, manufacture and sell RISC-V chips and software. It can design some processors based on it according to needs, such as server CPU, home appliance CPU, industrial control CPU and CPU always in the sensor.
The MIPS architecture is a processor architecture that takes a simplified instruction set and was developed in 1981. It can be said that it is a small branch of RISC, but it is different from RISC. After all, RISC is open source, and MIPS has developed better and more successful on its basis. The application of MIPS-based MCU involves many industries, and has great applications in industry, office automation, automobiles, consumer electronic systems and advanced technologies.
