An embedded system consists of two parts: hardware and software. It is a computer system designed to control and process various interrupt signals from the outside world, often with real-time computing constraints. Embedded systems typically include components such as MCUs, ASICs, FPGAs, and DSPs. The core components of embedded systems are various types of embedded processors, which are central to their operation. Currently, there are numerous popular architectures for embedded processors, with the 8051 architecture being one of the most widely used. The addressing space of embedded processors generally ranges from 64KB to 16MB, and their processing speeds range from 0.1 MIPS to 2000 MIPS. Commonly used packages have pin counts ranging from 8 to 144 pins.
