Embedded Solutions

An embedded system is a dedicated computer system that is part of a device or device. Typically, an embedded system is an embedded processor control board with control programs stored in ROM. In fact, all devices with digital interfaces, such as watches, microwave ovens, video recorders, cars, etc., use embedded systems, some embedded systems also contain operating systems, but most embedded systems are completely controlled by a single program logic.

Defined from the application object, an embedded system is a combination of software and hardware, and can also cover auxiliary devices such as machinery. The definition of embedded system generally recognized in China is: a special computer system centered on applications, based on computer technology, software and hardware can be tailored, and adapted to the strict requirements of application systems on function, reliability, cost, volume, and power consumption.

An embedded system device generally consists of an embedded computer system and an execution device.

     The embedded computer system is the core of the entire embedded system, which consists of hardware layer, middle layer, system software layer and application software layer. The execution device is also called the controlled object, which can accept the control commands issued by the embedded computer system and execute the prescribed operations or tasks. The actuator can be very simple, such as a tiny motor on a mobile phone, which turns on when the mobile phone is in the vibration receiving state; it can also be very complicated, such as a SONY smart robot dog, which integrates multiple micro control motors and various sensors. Thus, various complex actions can be performed and various state information can be felt.
