How to speed ADAS designs with a reversing camera reference design

How to speed ADAS designs with a reversing camera reference design

According to the National Highway Traffic Safety Administration (NHTSA), reversing cameras will substantially reduce injuries and deaths, especially among children. And rear-view technology is changing - rear-view video feeds are becoming intelligent systems that identify potential obstructions in real time - even when the vehicle is in motion. The camera itself is becoming a key element in the wider ADAS system.

More sophisticated rear view cameras incorporate a separate processing module that overlays trajectory lines on the screen, showing the driver obstacles that would be struck unless they change direction. In space-constrained vehicles and for system cost reasons, OEMs are requesting that the camera and processing module are now brought together in a single solution. This significantly increases the challenge for system suppliers in terms of packaging and thermal management.

Since the release of the original ‘Visconti’ processor in 2004, Toshiba has been a significant player in the market for automotive Image Recognition Processors (IRP). One of the leading, dedicated, IRPs available on the market today is the TMPV7502, primarily aimed at automotive ADAS applications including traffic sign recognition, pedestrian classification, forward collision warning and reversing cameras.

The TMPV7502 is a three-core RISC-based processor with on-board RAM and a total of five hardware-based accelerators for high-performance image recognition processing. These support Toshiba’s advanced CoHOG algorithms. The IRP realizes high performance with low power consumption of <1W through a highly parallelized approach rather than serial processing with a high clock frequency. This approach, along with the on-board CAN-bus interface, makes the TMPV7502 ideal for automotive image processing applications.

In order to demonstrate the capability of the TMPV7502 processor and to ease the design burden on customers, TEE has developed a comprehensive reference design for a reversing camera.

The reference design is based on four interconnected flex PCBs meeting the challenging requirement that the combined camera and image processing hardware fits in a space very similar to that previously occupied by the camera module alone.
