14bit A/D conversion at 105Msample/s
Analog Devices is claiming another industry breakthrough with the first 14bit ADC to run at 105Msample/s.
Using Analog Devices' high-speed Blackfin processor, the systems process images captured by cameras on the vehicle, and perform tasks such as traffic lane and object recognition, blind spot detection and headlight recognition.
This enables the systems to alert the driver and improve safety, including night vision, lane departure warnings, traffic sign recognition and reversing assistance.
"We chose ADI's Blackfin processor for our Tepla product because of its combination of high performance, low power consumption and low cost - which allows us to execute complex image processing and provide new applications for the automotive sector at an attractive cost", said Thomas Schilling, Business Director, Aglaia.

DSP needs no ASICs to run software basestations
Analog Devices has unveiled a new DSP equipped with Layer 1 software that together are claimed to reduce system costs of 3G infrastructure equipment by up to 50%.
"The key features for us are Blackfin's integration of powerful embedded processor and DSP functions in a single chip, and its dual high-speed parallel peripheral interfaces (PPI) for frame grabbing and transfer".
"The market for driver assistance and telematics systems are typically in the high-priced option category because discrete subsystems are required to perform a long list of specific functions, including GPS, mobile communications, operating information and vehicle diagnostics/prognostics", said Stefan Steyerl, Director of Marketing, EMP Europe, DSP and Systems Division Europe, Analog Devices "By utilising the low power, low cost characteristics of Blackfin, ADI is helping Aglaia migrate 'luxury' features to the mainstream".
Tepla was developed by Aglaia as a high performance, low priced electronic control unit (ECU) solution for driving assistance system software modules.
It also has applications in sectors such as surveillance and biometrics.
The Tepla system provides six IEEE1394b connectors on three different buses, CAN and LIN interfaces, and an Ethernet interface to connect multiple Teplas.
Four ADSP-BF561 Blackfin processors, each with two cores running at 600MHz, offer scalable processing power for image processing and other tasks.
Two other valuable features of the Blackfin processor for Tepla are the large on-chip memory of 328Kbyte, and its extended operating temperature range of -40 to +85C.
"Visual sensor systems have some decisive advantages over radar- or laser-based driver assistance systems", said Thomas Schilling.
"Firstly, the existing infrastructure for traffic routing is based on visual perception by humans".
"Secondly, visual systems are passive, and do not have any inherent potential hazards or risk of mutual inference".
"Most significantly, visual systems can be included in automobiles at a low cost, increasing the size of the potential market".
