Four categories of embedded processors [Copy link]

 

Embedded processors can be classified according to different characteristics such as their structure, performance and purpose. The following are four common embedded processor classifications:

1. General-Purpose Microprocessors :

   • Features : General-purpose microprocessors are designed for multiple purposes, have high performance and flexibility, and can run general-purpose operating systems (such as Linux, Windows, etc.).
   • Application : Common general-purpose microprocessors include the ARM Cortex-A series, Intel Atom series, etc., which are used in smartphones, tablets, network equipment, embedded industrial control systems, etc.

2. Embedded Microprocessors :

   • Features : Embedded microprocessors are specially designed for embedded systems, usually with lower power consumption and cost, as well as higher real-time performance and reliability.
   • Application : Common embedded microprocessors include ARM Cortex-M series, Microchip PIC series, etc., which are used for embedded control, sensor data processing, embedded network communication, etc.

3. Digital Signal Processors (DSP) :

   • Features : Digital signal processors are specially designed for digital signal processing applications. They have efficient floating-point operations and signal processing capabilities and are usually used in audio, video, communications and other fields.
   • Application : Common digital signal processors include TI TMS320 series, ADI Blackfin series, etc., which are used for audio processing, image processing, communication baseband processing, etc.

4. Application-Specific Processors :

   • Features : Customized processors are optimized for specific application areas or tasks and usually have the characteristics of high performance, low power consumption and low cost.
   • Application : Common custom processors include ASIC (Application-Specific Integrated Circuit) and FPGA (Field-Programmable Gate Array), which are used for dedicated computing acceleration, dedicated interface control, dedicated protocol processing, etc.

These classifications are not absolute; different types of embedded processors may have overlapping features, and the classification of embedded processors is constantly evolving as technology develops and needs change.
