Software accelerates FPGA development for edge computing

Thu, Sep 05, 2019

Software developers can realise up to 100x performance increase and reduce development time by up to a factor of 15, using CacheQ’s QCC Acceleration Platform, says the company.

The distributed heterogenous compute development environment provides a high-level language (HLL) software development platform for heterogeneous compute architectures. At its heart is the CacheQ Virtual Machine (CQVM). This is a complete application representation that can be analysed, partitioned, optimised and targeted to a variety of compute engines. Input is HLL code that is generated into CQVM, then optimised and partitioned. The final result are compute executables from the partitioned CQVM.

The CQVM allows extensive analysis and optimisation can be done before compute executable generation. Software developers can perform performance simulation, profile the compete virtual machine, view the CQVM to examine partitioning results and hot spots and analyse compute resource utilisation to accelerate design cycles.

To avoid partitioning challenges, requiring the development of compute engine-specific code, software developers write one application using the QCC Acceleration Platform. It automatically partitions an application across compute elements that can be combinations of processors and FPGAs. It supports both automatic and user-guided partitioning to deliver performance and reduce development time.

There is automatic pipelining to accelerate development. For example, CacheQ cites FPGAs’ fully pipelined execution time of a (N+ C)/(clock rate). For more acceleration, pipelined loops can be unrolled to deliver greater acceleration through a simple command line option with no code modification, adds CacheQ.

Traditional FPGA development requires users to rewrite their code and guarantee predictable memory access. The CacheQ offers tight integration with the memory subsystem and application code to deliver performance and reduce development time.

The Acceleration Platform’s proprietary multi-port arbitrated cached memory subsystem integrates with the CQVM to deliver up to 100 memory ports and Tbytes of memory bandwidth. In addition, malloc (C dynamic memory allocation) and complex pointer references are supported.

Charge e-bikes’ batteries wirelessly says Würth Elektronik

Thu, Sep 05, 2019

Developers of charging devices and charging stations can provide wireless battery charging for e-bikes and small electrical vehicles, says Würth Elektronik, as it unveils its support for developers to implement individual charging concepts.

Besides providing expert know-how in the form of training seminars or on-the-spot development support, Würth Elektronik has also designed many development kits that help manufacturers to bring their products to the market more swiftly.

“When a battery pack is charged by cable, you have to reckon with between 2,000 and 5,000 plug cycles over the battery’s life cycle. Especially because users generally recharge batteries that are not fully discharged on the go to ensure mobility, in many cases the charging sockets and plugs wear out faster than the actual batteries themselves,” explains Sven Lerche, business development manager New Mobility at Würth Elektronik eiSos. “Repairing charging sockets or charging devices is rarely an economically viable option, and wireless charging is an extremely attractive alternative. Then you’ve also got a number of other advantages like the high convenience factor, the fully enclosed design, and the insensitivity to environmental factors.”

Würth Elektronik explodes three popular misconceptions about wireless power: inefficiency, safety and expense.

When the recommended position of the device is even only roughly adhered to – an aspect that can be enhanced by the mechanical design – efficiency is about 95 per cent, says the company. It adds that the fear of electric shock or suffering burns is also unfounded because the industrial standards prescribe an automatic switch-off device that cuts in as soon as a foreign body gets between the charging coil and the receiver coil. The technical effort required for this is minimal, Würth Elektronik confirms.

As for expense, the plug and socket are replaced by wireless power coils and a slightly more sophisticated electronics, which ultimately can even result in a cost-neutral solution, insists the company.

Würth Elektronik eiSos Group manufactures electronic and electromechanical components and is one of the largest European manufacturers of passive components, with production sites in Europe, Asia and North America.

6/10W power modules from XP Power are for industrial and ITE applications

Thu, Sep 05, 2019

Two wide input range chassis and DIN rail mount DC/DC converters introduced by XP Power are claimed to offer simple and rapid installation into a variety of industrial and ITE applications.

The DTE06 and DTE10 DC/DC converters provide 6.0 and 10W of power and offer a 4:1 input range, giving a wide tolerance for fluctuating supplies. Nominal inputs are 12/24V DC and 24/48V DC; the converters cover inputs between 9.0 and 75.0V DC.

The converters are supplied fully-potted in chassis mount format with screw terminals to save time when mounting and for reliable connection. A DIN rail mount is optionally available for use in control cabinets and household consumer units.

A power-good LED indicator confirms correct operation.

All DC/DC converters in both series are IEC/UL/cUL 62388-1 safety approved and offer 3.0kV DC isolation between the supply and load. They also comply with EN55032 Class A emissions with no external components, meaning that no additional filtering is required for EMC compliance.

The device has input under-voltage, short circuit and over-load protection. To control the DC/DC converters there is a remote on/off feature.

The rugged DTE06 and DTE10 series operate over a -40 to +105 degrees C temperature range and deliver full rated power at temperatures up to +80 degrees C.

The DTE06 & DTE10 series are offered with a three-year warranty and are available directly from XP Power or from Digi-Key, element14, Farnell, Mouser, RS Components and approved regional distributors.

Wide-angle thermal MEMS sensor contactless offers Omron’s widest field of view

Wed, Sep 04, 2019

Omron Electronic Components Business Europe has added a wide angle 32 x 32 element version of its D6T MEMS thermal sensor. It offers the widest field of view that Omron has ever delivered, says the company.

The Omron D6T-32L-01A can view across 90.0 x 90.0 degrees, enabling it to encompass a wide area, such as a whole room, from a single point. The sensor offers contactless measurement of temperatures of 0 to 200 degrees C in ambient temperatures of -10 to + 70 degrees C.

Omron D6T MEMS thermal sensors are based on an IR sensor which measures the surface temperature of objects without touching them using a thermopile element that absorbs radiated energy from the target object. They incorporate a MEMS thermopile, custom designed sensor ASIC and signal processing microprocessor and algorithm in a tiny package. According to Omron, the D6T offers the highest signal-to-noise ratio (SNR) in the industry. It converts the sensor signal to a digital temperature output giving a straightforward interface to a microcontroller. The design of the D6T, which measures only 14 x 8 x 8.93mm for the largest 32 x 32 element version, makes it well-suited to temperature detection in a range of IoT and other embedded applications.

The D6T-32L is one of three D6T variants by Omron, joining the 1×8 D6T-8L-09H and the 4×4 D6T-44L-06H, offering 54.5 x 5.5 and 44.2 by 45.7 degrees respectively. These two devices offer contactless temperature measurement between 5.0 to 200 degrees C at ambient temperatures of 5.0 to 45 degrees C.

The D6T sensors can be used to detect abnormal temperatures in industrial equipment on the production line to monitoring of food and other temperatures in the kitchen. This can save costs, allowing preventative maintenance to be undertaken in a timely manner, points out Omron, and can even save lives. They can also detect the presence and location of people in a space accurately and reliably.
