MCU (microcontroller unit), also known as Single Chip Microcomputer Microcomputer) or single-chip microcomputer, which combines CPU with memory, counter, USB, A/D conversion, Peripheral interfaces such as UART, PLC, and DMA are integrated on a single chip to form a chip-level controller that is responsible for data processing, diagnosis, and calculations. Generally, MCUs are divided into 8, 16 and 32-bit models according to the number of data bits processed by the CPU.

CPU (central processing unit) is based on von Neumann architecture, computing and storage Separation, using control flow driver mode, reads instructions, decodes them and executes them, which is suitable for processing serial tasks with high complexity and low repeatability.

GPU (graphics processing unit), also known as display core, visual processor, display A chip is a microprocessor that mainly performs image and graphics related operations.

DSP (digital signal processing) chip is a type of chip that can realize digital signals Complex computing chips that process functions

FPGA (Field-Programmable Gate Array) is a reconfigurable chip In circuit design, sequential logic is implemented through flip-flops, and combinational logic is implemented through lookup tables.

NPU (neural network processing unit) is a general term for new processors based on neural network algorithms and acceleration. It is usually designed using a data-driven parallel computing architecture.

Visual perception mainly refers to the image sensor, which divides the light image on the light-receiving surface into many small units and converts it into An electronic component that can provide electrical signals; image sensors include CMOS and CCD.

LiDAR refers to a type of sensor that uses laser light for detection and ranging. Lidar mainly includes laser emission The structure of the scanning system, laser receiving part and information processing part is relatively complex.

Millimeter wave radar is a radar detector that works in the millimeter microwave frequency band. The radar continuously emits millimeter wave beams. Surrounding target obstacles emit signals back, detect the presence of the target based on the emitted signal, and calculate its position and speed. Degree and angle information.

Ultrasonic radar uses the principle of piezoelectric effect to drive the vibration of the sensor head chip with electrical signals to generate mechanical sound wave signals. Radiation spreads out through space. Use a single transceiver to implement ultrasonic ranging detection, including internal driver transmitter, receiver, echo signal processing, frequency generator, control unit, memory, communication interface, power supply and other modules.

Infrared image sensors can convert detected infrared radiation into image information visible to the human eye. Even at night or in dark weather, you can clearly observe the distant environment. Unlike visible light images, the red color of objects The amount of external radiation energy is directly related to the temperature of the object surface, usually with a wavelength of 700~1070nm.

Visual perception mainly refers to the image sensor, which divides the light image on the light-receiving surface into many small units and converts it into An electronic component that can use electrical signals.

Energy conversion device that converts speech signals into electrical signals

By emitting near-infrared light, vehicles generally use wavelengths of light that are invisible to the human eye, mostly 850nm and 940nm.

Generally refers to switching power supply, used for DC voltage conversion, commonly used Buck type, boost type, buck-boost type.

Low dropout regulator is a low dropout linear regulated power supply, used for DC voltage reduction.

Power Management Unit is a power management chip with richer functions than LDO, DCDC, etc., such as a watchdog, multiple working modes, multiple LDOs, DCDC, output voltage can be configured through registers, and integrated IO, CAN/LIN transceiver device, SPI, etc.

Chips used in battery management systems, including charging management modules, power management modules, protectors, and monitors and balancer etc.

Insulated gate bipolar transistor) is an insulated gate bipolar transistor, which is a high-voltage energy conversion and transmission device. The core device that loses. It combines the advantages of high input impedance of MOSFET and low conduction voltage drop of GTR (power transistor).

A device that exists in an independent form and performs key generation, encryption and decryption. It has an independent processor and storage unit inside, which can store keys and characteristic data to ensure the authenticity, confidentiality and integrity of interactive data and secure startup. security features such as movement, secure storage, and secure access control.

The hardware security part integrated in processor units such as MCU or AP, including HSM, inSE, etc., can have independent CPU, memory, etc. It has hardware isolation or logical isolation boundaries, separates the processing of security-sensitive data from the processing of other data, and has certain security protection capabilities. According to the security requirements, security functions can be provided within the security boundary, but other parts outside the security part usually do not have security protection capabilities.
