Integrated open image signal processor adds to R-Car SoC applications

An integrated open image signal processor (ISP) from Renesas Electronics can be integrated on the company’s R-Car V3M and R-Car V3H SoCs to speed the development of automotive smart camera applications.

According to Renesas, integrating the ISP on the R-Car V3x SoCs and leveraging MM Solutions’ Automotive Camera Development Kit (AutoCDK), enables automotive Tier 1s to simplify the sensor calibration and tuning process for camera applications, including front camera and surround view to reduce the time to market.

The open ISP solution supports a range of development needs, from low-level-programming ISP capabilities via the open interface to the AutoCDK for users to jumpstart development using the MM Solutions’ tools.

Autonomous vehicles will be required to sense their environments, with smart cameras in front and surround view systems used to detect traffic signs, lanes, pedestrians, vehicles, and other obstacles in real time.

High performance computer vision requires highly reliable, highly configurable ISPs that support high dynamic ranges in challenging driving situations as well as low-noise performance and imagery perception close to that of a human eye’s level – or beyond, explains Renesas. Drivers will want to see a realistic visual representation of the surrounding of the car, where the ISP plays an important role for image adjustment.

In collaboration with MM Solutions, Renesas has developed an open ISP solution that helps users tune and control their sensors to support both human vision and machine vision. Integrating the ISP vision processing software onto the R-Car V3x SoCs provides a camera-neutral approach, offering camera manufacturers and Tier 1s the flexibility to work with ECUs and sensors of choice.

Jean-Francois Chouteau, vice president of the Automotive Solution Business Unit, Renesas Electronics, said: “Developing the software solution as part of the Renesas autonomy platform allows customers to take advantage of robust off-the-shelf middleware as well as privileged access to the image quality expertise of our partner MM Solutions.”

“Turnkey ISP solutions that support multiple platforms are essential to achieving excellent camera quality while meeting increasingly shorter time-to-market challenges for front camera, surround view, and other automotive camera applications,” added Ivan Poibrenski, managing director of MM Solutions.

“Achieving high dynamic range and LED flicker mitigation simultaneously is the key challenge for ADAS camera systems,” said Tsutomu Haruta, deputy senior general manager, Sony Semiconductor Solutions. “The combination of Renesas’ ISP solution and Sony’s image sensors enables our automotive customers to . . . realise a superior image quality.”

Mass production of the Renesas R-Car V3M and R-Car V3H SoCs is scheduled to begin Q2 2019 and Q3 2019, respectively. The AutoCDK from MM Solutions will be available in November 2018.

 Renesas will demonstrate the Open ISP using the Renesas R-Car V3M, MM Solutions’ AutoCDK, and Sony’s IMX390 image sensor in booth 6 at AutoSens 2018, September 17-20, 2018, Brussels, Belgium.

H-bridge motor driver IC meets demand for low voltage, high current drive

For DC brushed motors and stepping motors, the TC78H651FNG is a dual H-bridge driver IC announced by Toshiba Electronics Europe.

The TC78H651FNG delivers performance at a low voltage (down to 1.8V) and high current (up to 1.6A) for equipment powered by dry-cell batteries. It is suitable for motor applications such as cameras and compact printers using 3.7V lithium-ion batteries, toys and home appliances, smart meters, and electronic locks using two 1.5V dry batteries, and devices using 5V USB power supplies.

IoT advances and wireless technologies are driving demand for applications that can be remotely controlled by smartphones and tablets, in turn stimulating demand for battery-powered motor control, argues Toshiba. Existing H-bridge driver ICs use bipolar technology which is stable at low voltage. However, the associated high levels of current consumption shorten battery life and increase losses leading to reduced motor torque.

The TC78H651FNG uses Toshiba’s DMOS process that is suitable for low voltage drives to reduce losses and current consumption, ICC is around 0.6mA in operating mode and virtually zero when in standby mode, claims Toshiba. This achieves a longer battery life and stable low voltage operation. The reduced on resistance of 0.22 Ohm for the high and low sides combined reduces IC losses and improves torque in the motor, even when powered at 1.8V.

The device is housed in a 5.0 x 6.4mm, 0.65mm pitch TSSOP16 package and supports forward, reverse and stop rotation modes. Inbuilt error detection functions for over-current protection, thermal shutdown and under-voltage lockout all contribute to ensuring a safe system.

Network traffic analytics aids efficiency

At this week’s Mobile World Congress Americas, ipoque, a Rohde & Schwarz company, will introduce R&S Intra, intelligent network traffic analytic software.

The software is designed for communication service providers (CSPs) to access real-time reporting capabilities that enable CSPs to efficiently glean data insights on subscribers across networks, and to make decisions to enhance organisational efficiency, says Rohde & Schwarz.

CSPs have to be able to manage ever-increasing volumes of data from IoT-enabled devices. The number of connected devices is expected to double between 2018 and 2020, boosted with the arrival of 5G technology.

Intra offers connectivity options up to 100 Gigabit Ethernet and a processing speed to provide CSPs with data insights at a reporting rate of one second for actionable, real-time insights that can be used across CSP business units including network planning, product marketing and customer care. With flexible analytics application program interfaces (APIs) that seamlessly connect to any big data system, R&S Intra allows all CSP stakeholders to synchronise and optimise data analytics activities to drive decisions across business units, reducing costs and improving overall business performance, says Rohde & Schwarz.

Dirk Czepluch, CEO at ipoque said: “CSPs need to operate efficiently – in terms of both securing and acting on network data insights. Data shows its true value when analyzed across departments, combined with other sources of information and amassed in a conclusive, multi-purpose pool. . . . giving them the ability to extract value from their networks, use data in a more agile way and accelerate time to action.”

R&S Intra has proprietary deep packet inspection (DPI) engine R&S Pace 2 and real-time packet processing to offer fine-grained information on network traffic, subscriber sessions and network metadata. It can be easily integrated with existing systems, fully virtualised and scaled up as needed. With a standard and vendor-independent big data export, R&S Intra also allows CSPs to reuse collected data for future use cases.

Visit ipoque at Rohde & Schwarz’s booth in South Hall #S-2814 at Mobile World Congress Americas (12 to 14 September) in Los Angeles, California, USA.

Q-Free and Silicon Labs develop sensor to find a parking spot

Q-Free and Silicon Labs have collaborated on a new outdoor parking IoT sensor that helps drivers find vacant parking places in towns. The companies have created Q-Free’s ParQSense smart parking sensor, which uses the Silicon Labs’ EZR32WG Wonder Gecko wireless microcontroller for control and sub-GHz connectivity. The sensor was deployed as a pilot this year in the UK, Netherlands, Sweden, Norway and North America, and will be released for commercial use this month.

Q-Free has focused its resources on developing ways to reduce traffic flows. It provides a range of transportation technologies including electronic tolling, vehicle counters, surveillance technologies and parking management solutions. The ParQSense smart parking sensor is one of the company’s first sensor products to support outdoor parking needs. According to an INRIX study, 20 per cent of traffic in urban areas can be attributed to drivers searching for parking spots.

“To develop an IoT sensor solution for outdoor parking that would succeed in today’s market, we had to deliver a combination of low-power, long-range wireless connectivity and high performance,” said Brage Blekken, a project manager in Q-Free’s R&D department. “Silicon Labs helped us overcome this challenge by providing best-in-class wireless technology capable of transmitting data over long distances in the sub-GHz band,” he added.

Many existing outdoor parking sensors on the market had accuracy limitations, and struggled with wireless capabilities and interference from cellular networks commonly associated with urban environments, reports Q-Free.

The Q-Free ParQSense option uses dual radar and magnetic field technology to sense with 99+ per cent accuracy whether a vehicle is present in a parking space. The application transmits data to centralised base stations over long distances using narrowband sub-GHz wireless connectivity.

Q-Free supplies intelligent transportation systems comprising tolling, parking, info-mobility, traffic management and C -ITS/connected vehicle solutions. It was founded in 1984 and headquartered in Trondheim, Norway, the company has over 400 employees, offices in 18 countries.
