FAQ about Embedded - Microprocessors
-
1. Is an embedded microprocessor a computer?
An embedded microprocessor is a computer. An embedded microprocessor is a computer chip designed specifically for embedded systems and used in a variety of devices and equipment to provide additional functions. It is the core component of an embedded system and is responsible for executing instructions, processing data, and controlling other hardware devices.
Embedded microprocessors have similarities with CPUs in general-purpose computers, but there are also significant differences. Embedded microprocessors evolved from CPUs in general-purpose computers, with processors above 32 bits and high performance, but their design focuses on specific applications such as networking, communications, audio, video, or industrial control. In actual applications, embedded microprocessors only retain functional hardware that is closely related to embedded applications, and remove other redundant functional parts to achieve the lowest power consumption and resource utilization. -
2. What is the difference between a general-purpose processor and an embedded processor?
Similarities: The basic design principles are the same, and both are chips that provide computing power.
The differences are as follows:
A. Different references
1. General-purpose processor: refers to CPU chips for servers and desktop computing.
2. Embedded processor: It is the core of the embedded system and is a hardware unit that controls and assists the operation of the system.
B. Different characteristics
1. General-purpose processor: The workload is mainly non-numerical and irregular scalar applications (this load is also the workload characteristic of current transaction processing and Web service servers). The method to achieve high performance is mainly to develop instruction-level parallelism.
2. Embedded processor: It has a very powerful storage area protection function. This is because the software structure of the embedded system has been modularized. In order to avoid the cross-interaction of errors between software modules, it is necessary to design a powerful storage area protection function, which is also conducive to software diagnosis.
C. Different functions
1. General-purpose processor: The superscalar structure is used as the main means to improve the performance of the processor. This structure maintains compatibility with the RISC structure on the instruction interface, but is dynamically scheduled by hardware internally to achieve parallel execution of multiple operations.
2. Embedded processor: It has strong support for real-time multitasking, can complete multitasking and has a short interrupt response time, thereby reducing the execution time of internal code and real-time core to a minimum.

3. Is A chip an embedded system?
A chip is part of an embedded system. A chip usually refers to a microprocessor or controller used in a specific device or system. These devices can be smartphones, tablets, smart home devices, etc. The A chip in these devices is the core component of the embedded system, responsible for processing and executing specific tasks and control functions.
An embedded system is a computer system designed for a specific application, usually consisting of hardware and software. The hardware part includes processors, sensors, actuators, etc., while the software part includes operating systems, applications, etc. Embedded systems are usually small in size, compact in structure, and low in power consumption, and are widely used in industrial control, consumer electronics, automotive electronics, and other fields.
