AVR and AVS are two different concepts. Their core differences are application scenarios, technical functions and industry affiliations, as follows:
1.Definition and Industry AVR: Full name: Automatic Voltage Regulator or AVR microcontroller (developed by Atmel).
Domain: If it refers to an automatic voltage regulator, it belongs to electrical and electronic equipment used to stabilize generator output voltage of a generator.
If it refers to an AVR microcontroller, it belongs to the field of embedded systems, is an 8-bit RISC architecture microcontroller.
AVS: Full name: China's independently developed audio and video coding standards.
Domain: Digital audio and video compression and transmission, information technology standards.
2.Core Functions and Technologies AVR
Function: Stabilizes generator output voltage by adjusting the excitation current to prevent equipment overvoltage or undervoltage damage.
Technical features: Voltage setting, stability adjustment, low frequency protection.
Adapt to load change and provide stable power supply.
AVR (Microcontroller Virtual Machine)
Function: As a microcontroller, it executes programs to control external equipment (such as home appliances and industrial instrumentation).
Technical features:
High-speed RISC architecture, high instruction execution efficiency.
Built-in Flash, EEPROM and SRAM support in-system programming.
Low power consumption, strong anti-jamming ability, suitable for embedded system.
AVS (Audio/Video Codec Standard)
Features: Compresses digital audio and video data, reduces storage and transmission costs, and supports high-definition and ultra-high-definition video encoding.
Technical features:
Efficient compression: The coding efficiency is 2-3 times that of MPEG-2 Employs intra-frame prediction, motion compensation and transformation quantization.
