Rearview panoramic reversing driving assistance system solution
In addition to reducing the system cost of the reversing scheme, the scalability of the processor is particularly important. IDH Vision Blue's panoramic parking assistance driving system solution uses BlacKfin series processors, unique MSA architecture, and a processor with good scalability can effectively reduce the number of chips used in the system, reduce system costs, and reduce PCB area.
The rear view panoramic reversing assisted driving system is a safety assisting device when parking or reversing a car. Help the driver to eliminate the defects of blind spots and blurred vision, and improve driving safety.
Components of rear-view panoramic reversing driving assistance system
. Main processor: it is the core of the reversing driving assistance system
. Acquisition circuit: laser, radar and other various sensors
. Output: usually sound or video images, assist the driver to reverse the car, and alarm the emergency
. Power management: Manage system power
The processor must ensure that it can process all kinds of information collected in real time, including the video image information collected by the CCD, the information returned by the sensor, etc., which puts high requirements on the performance of the processor.
In addition, in terms of reducing system cost, the scalability of the processor is particularly important. A processor with good scalability can effectively reduce the number of chips used in the system, reduce system cost, and reduce PCB area.
Vision Blue's BlacKfin series processors are a converging platform. It uses a unique MSA architecture, which has the advantages of excellent performance and good scalability. It is very suitable for rear-view panoramic reversing assistance driving systems.
In addition, Vision Blue can provide customers with low-level algorithms to complete solutions, reducing development costs and development cycles.

The advantages of BlacKfin series DSP in this field :
. High performance: BlacKfin is a 16 / 32-bit embedded processor. Its main frequency is up to 600MHz. It also supports SIMD. It also contains a special instruction set designed for image processing, which can meet the rear-view reverse driving assistance system Signal processing performance requirements.
. Low power consumption: BlacKfin adopts low power consumption and low voltage design principles. Its dynamic power management and the ability to change the operating voltage and frequency at the same time can significantly reduce the overall power consumption. Compared with only changing the operating frequency, changing the voltage and frequency at the same time can greatly reduce power consumption.
. High reliability: BlacKfin chip also has the advantages of reliable quality, wide temperature range, strong anti-thousand interference capability, etc., to ensure that the processor can still work normally in various harsh environments.
. Perfect compatibility: BlacKfin series processor codes are fully compatible, customers can use different model processors, the same code to customize high, medium and low. End products, not only save development time, but also save development and maintenance costs.
. Excellent convergence platform: BlacKfin series processors integrate rich peripheral interfaces, and support more functions without increasing system power consumption, size, and cost.
. Rich code base: Vision Blue Company can provide a variety of highly optimized algorithm bases and time to market of products. Such as PPI, GAN, etc., this integration allows Blackfin to be used to reduce customer development time and development costs, and shorten customer time to market.
Vision Blue Company has been paying attention to the development of automotive electronics for a long time. Its analog chips such as ADC DAC and amplifier are widely used in automotive electronics.
"Lithium battery" refers to a battery made of lithium metal or lithium alloy as a negative electrode material, using a non-aqueous electrolyte solution.It has a high energy density.Compared with high-capacity nickel-cadmium batteries, the energy density is twice as high.High voltage. The average service voltage is 3.6v, which is three times higher than nickel-cadmium and nickel-hydride batteries.The use voltage is even and the high capacity, the widespread use temperature -20 degrees -60 degrees, the charge and discharge life is long, after 500 discharges its capacity at least has more than 70%.Due to the characteristics of high energy density, high voltage and stable operation, lithium battery is widely used.
