The imaging and vision DSP core offers up to 13X performance boost, with an average of 5X less energy usage on vision tasks compared to the previous generation IVP-EP imaging and video DSP.
The Tensilica Vision P5 DSP is built for applications requiring ultra-high memory and operation parallelism to support complex vision processing at high resolution and high frame rates. As such, it is ideal for off-loading vision and imaging functions from the main CPU to increase throughput and reduce power.
Pre-Collision Assist with Pedestrian Detection uses radar and camera technology to scan the roadway ahead and, if a collision risk with a vehicle or pedestrian is detected, provides a warning to the driver. If the driver does not respond in time, the system can automatically apply up to full braking force to help reduce the severity of or even eliminate some frontal collisions.
At the Frankfurt Auto Show, TRW Automotive Holdings Corp. chairman and chief executive officer John Plant described the firm’s next generation of safety technologies to help enable semi-automated driving:
“Over the next decade, active safety systems will become increasingly intelligent as greater efforts are made to reduce the number of road fatalities worldwide. More automated functions will be introduced that will operate continuously in certain situations in addition to providing emergency support when needed.”
At the Society of Automotive Engineers (SAE) Convergence 2012 conference in Detroit, Xilinx, Inc. unveiled its automotive ARM®-processor based Zynq™-7000 All Programmable system-on-a-chip (SoC) platform, which targets next-generation advanced driver assistance systems (ADAS).
Xilinx said the Zynq-7000 can reduce both cost and time-to-market for driver assistance systems by using programmable system integration to lower bill-of-materials (BOM) and meet sophisticated technical requirements for driver assistance systems – especially image-to-vision and in-vehicle networking requirements.
At Electronica China, Melexis introduced the MLX90620 FIRray sensing device, which uses the company’s non-contact temperature measurement technology to create a cost-effective thermography solution. Covering a -20°C to +300°C temperature range, the 16 x 4 element far infrared (FIR) thermopile sensor array produces a map of heat values for the target area in real time, avoiding the need to scan the area with a single point sensor or use an expensive microbolometer device.
The driver’s perspective in the latest cars emerging from leading OEMs more and more resembles the pilot’s view in a modern fighter plane. With applications like heads-up displays on the windshield and 360-degree surround view, luxury car drivers won’t be engaging in dogfights, but are now enjoying the elimination of blind spots on the road and the kind of pedestrian and lane tracking detection capabilities formerly reserved for incoming bogies. All this interactivity requires a high degree of parallel processing power and the ability to fully utilize the smart cameras being built in around the automobile.
Pre-collision braking/adaptive cruise control system capable of pedestrian detection, lane departure, sway warning
Optional in ‘13 Legacy and Outback
Subaru of America, Inc. has announced the debut of its EyeSight™ driver assistance system, an option on 2013 Legacy and Outback models that will subsequently appear on other products in the Subaru line-up. EyeSight integrates adaptive cruise control, pre-collision braking, and vehicle lane departure warning. The new technology, which can also detect obstacles in front of a parked car and limit potential damage in an impact, will become available later this year.
STMicroelectronics and Mobileye N.V. announced that the two companies are co-developing the next generation of their System-on-Chip processor for the vision-based driver-assistance segment of the automotive market.
The EyeQ3 and EyeQ3-Lite will be the first members of a third-generation family in the co-operation between ST and Mobileye, which began in 2005. The EyeQ1, now in production at several car makers, provides lane-departure warning (LDW), adaptive-headlight control (AHC), traffic-sign recognition (TSR), collision avoidance via radar-camera fusion, and forward collision warning (FCW).
