Freescale multi-camera panoramic parking assist system and ADAS products
Freescale mainly focuses on the ADAS applications of forward vision (lane deviation and tracking, blind spot detection), rear vision (smart parking and ranging), and surround vision (parking). Freescale has designed many microcontroller products for future ADAS systems.
Freescale and OminiVision, Broadcom launched the world's first Ethernet-based surround-view parking system. Freescale's Qorivva MPC5604E 32-bit MCU, based on Power Architecture technology, manages video transmission and camera control, reducing the required communication bandwidth to less than 100 Mbps. Cars usually require 4 or 5 low-voltage differential signal cables to transmit video data The price of a cable is about 10 dollars.

ADAS needs higher bandwidth bus to solve the problem because of information volume and high resolution. Ethernet is the best solution. MPC5604E MCU and i.MX6 series multimedia processors provide a good Ethernet-based surround view solution. MPC5604E can transfer the camera data to the central processor i.MX6 via Ethernet. The i.MX6 series includes single-core, dual-core, and quad-core families based on the ARM Cortex-A9 architecture, and combines a strong ecosystem. It is an ideal platform for developing terminal device combinations based on a single hardware design. It has a very powerful ability to process images and can quickly control current information.
Compared with the ADAS products launched by competitors, Freescale's dedicated image processor has a powerful 32-bit MCU built in. This MCU combines image processing IC, motor controller, Sigma Sensor, Ethernet chip, etc. , Now the industry's most integrated ADAS image processor, can save ADAS system integration manufacturers 15% cost and 15% printed circuit board (PCB) space, and because the single chip failure rate is more low Helps improve the reliability and safety of automotive systems.
