Mobileye Unveils its 4th Gen Vision Processor

PRNewswire: Mobileye introduces its 4th generation system-on-chip, the EyeQ4, consisting of 14 computing cores out of which 10 are specialized vector accelerators for visual processing and understanding. The first design win for EyeQ4 has been secured for a global premium European car manufacturer for production to start in early 2018. The EyeQ4 would be part of a scalable camera system starting from monocular processing for collision avoidance applications, in compliance with EU NCAP, US NHSTA and other regulatory requirements, up to trifocal camera configuration supporting high-end customer functions including semi-autonomous driving. The EyeQ4 would support fusion with radars and scanning-beam lasers in the high-end customer functions.

"Supporting a camera centric approach for autonomous driving is essential as the camera provides the richest source of information at the lowest cost package. To reach affordable high-end functionality for autonomous driving requires a computing infrastructure capable of processing many cameras simultaneously while extracting from each camera high-level meaning such as location of multiple types of objects, lanes and drivable path information," said Amnon Shashua, cofounder, CTO and Chairman of Mobileye. "The EyeQ4 continues a legacy that began in 2004 with EyeQ1 where we leveraged deep understanding of computer vision processing to come up with highly optimized architectures to support extremely intensive computations at automotive compliant power consumption of 2-3 Watts."

The EyeQ4 provides "super-computer" capabilities of more than 2.5 teraflops within a low-power (approximately 3W) automotive grade system-on-chip.

EyeQ4-based ADAS uses computer vision algorithms like Deep Layered Networks and Graphical Models while processing information from 8 cameras simultaneously at 36fps. The EyeQ4 will accept multiple camera inputs from a trifocal front-sensing camera configuration, surround-view-systems of four wide field of view cameras, a long range rear-facing camera and information from multiple radars and scanning beam lasers scanners. Taken together, the EyeQ4 will be processing a safety "cocoon" around the vehicle – essential for autonomous driving.

Engineering samples of EyeQ4 are expected to be available by Q4 2015. First test hardware with the full suite of applications including active safety suite of customer functions, environmental modeling (for each of the 8 cameras), path planning for hands-free driving and fusion with sensors, is expected to be available in Q2 2016.

Samsung Announces 8MP RWB ISOCELL Sensor

Business Wire, Samsung Tomorrow: Samsung’s 8MP ISOCELL RWB CMOS image sensor, the S5K4H5YB, is aimed to front-facing mobile cameras. By combining ISOCELL technology with the newly developed RWB (Red-White-Blue) color filter, the new image sensor enhances light sensitivity and color fidelity, allowing an improvement of over 3 dB in SNR in low light settings. In addition, unlike other types of color pattern configurations, the high similarity between the RWB and RGB patterns eliminates the need for an RGB convertor in a RWB filter, which prevents unnecessary color deviation.

Physical barriers between each ISOCELL pixel allow 30% decrease in crosstalk and 30% increase in full-well capacity when compared to "conventional" BSI sensors, possibly, S5K4H5YC.

Samples of the 8 MP RWB ISOCELL image sensor are available for customers and mass production of the product is scheduled for Q2 2015. Incidentaly, the S5K4H5YB has already been announced a year and a half ago. By that time, Samsung said "The S5K4H5YB is currently sampling to customers with mass production scheduled for Q4 2013." However, in the earlier announcement, Samsung has not mentioned RWB CFA.

Samsung S5K4H5YB product page says that it's already in production:

Freescale Presents Automotive Vision Processor

Business Wire: Freescale introduces the S32V vision microprocessor, said to be the first automotive vision SoC with the requisite reliability, safety and security measures to automate and ‘co-pilot’ a self-aware car. “Many automotive vision systems available today are based on consumer-oriented silicon solutions originally designed to enhance gaming graphics or run smartphone apps. But in a new era where cars will serve as trusted co-pilots, utilizing consumer-oriented silicon is fundamentally unwise,” said Bob Conrad, SVP and GM of Automotive MCUs for Freescale. “Relying on anything less than automotive-grade silicon to take control of a vehicle and make critical driving decisions is simply not acceptable – not for me, not for my family and not for my customers.

The S32V vision microprocessor integrates the 2nd generation CogniVue APEX-642 core image processing technology, as well as four ARM Cortex-A53 cores. Full market availability for the S32V is expected in July 2015.
