MILPITAS, CA – September 1, 2010 – Linear Technology announces the LTC6991, a simple, accurate low frequency clock specifically designed for long duration timing applications. The LTC6991 is the latest part in the TimerBloxTM family of versatile silicon timing devices, in which an accurate programmable oscillator is combined with precision circuitry and logic. An extremely wide programmable frequency range allows the clock to operate with a period from 1ms to 9.5 hours. This makes the LTC6991 useful for intervalometers, watchdog timers and periodic wake-up timers with minimal components and effort.

The LTC6991 is simply programmed, using 1 to 3 resistors, with a maximum frequency error that is guaranteed to be less than 1.5%. The LTC6991 offers glitch-free, first cycle accurate start-up within 500us of power, and a reset function is available to truncate the output pulse and hold the output in a high or low state. The polarity of the reset input and the output signal can be configured for active-low or active-high operation. In addition, the output frequency of the LTC6991 can be dynamically controlled via a separate control voltage.

TimerBlox devices are solid state and can be operated under high acceleration, vibration and temperature extremes. No timing capacitors, no crystals, no microcontroller and no programming are required. They offer higher accuracy, stability and lower power consumption than typical resistor/capacitor-based oscillators. The 20mA source and sink capability enables direct driving of opto-isolators for electrical isolation. Fully specified over the temperature range of -40°C to 125°C, the TimerBlox parts are suitable for demanding automotive and industrial environments, where many oscillators and microcontrollers are unable to operate. The small SOT23 footprint allows each timing device to be placed at the point of use, without routing signals over long distances, providing an ideal timer for space-limited applications such as handheld and portable devices.

“With the LTC6991, the designer can forget about big crystals, rows of counters and the headaches of programming,” says Doug LaPorte, design manager for Linear Technology. “The LTC6991 is extremely easy to use.”

The LTC6991 is now available, priced starting at $1.35 each in 1,000-piece quantities. Other TimerBlox devices will be introduced over the next month. For more information, visit www.linear.com/6991.

Bel Air, MD, 31 August 2010. Stone Ridge Technology today announced integration to the popular Impulse C to FPGA toolset. The integration enables software developers to write HLL (high level language) algorithms that rapidly compile to optimized RTL (run time language) targeting Stone Ridge’s RDX-11 FPGA board and development kit. For designs with significant non-sequential logic the speed improvements can be 10 – 100x. Compared to hand coded RTL methodologies, the design entry can take two thirds the time and iterations one eighth the time.

According to recent research, up to 1/3 of design teams are considering using an HLL to develop applications for hardware. The most common languages mentioned are C-based. The reasons given are time to prototype, plentiful existing intellectual property, and the fact that the increasing gate count of modern FPGAs makes manual design methods too slow for populating entire systems on a chip. Users from NASA to Wall Street are deploying HLL programmed FPGAs for applications such as image capture and financial feed processing.

Applications currently in use at Stone Ridge using ImpulseC center around high-speed feeds of data, images or signals. The integration to the new RDX development kit brings to reconfigurable computing C programmable cutting-edge FPGA technology with high bandwidth and ample memory to achieve maximum processing power. Specifically regarding accelerated network processing, Stone Ridge boards work with Impulse C to enable software developers to move critical path network interface processes to hardware, where they run faster in multiple streams without the overhead of an operating system.

The integration provides C based links to hardware features and busses on the FPGA and RDX-11 board such that software developers can accelerate on the board without writing hardware controllers. Processes run as custom streaming cores in dedicated FPGA hardware without an operating system, to maximize throughput and reduce power consumption. Packet data integrity is increased when compared to microprocessor based single- or dual-stream solutions.

“Many of our customers were interested in C-based tools. Impulse is a natural choice because of its broad based adoption across many industries and its place in the market.” commented Vincent Natoli, President of Stone Ridge Technology; he continued “We think the option of C-based algorithm development via Impulse’s products will open the door to high performance reconfigurable computing on FPGAs to many groups not trained in HDL’s. Network processing solutions in particular, which we’ve investigated in some detail, will benefit from ANSI-C configurable hardware accelerated solutions that can shave off 10’s of microseconds of latency and deliver improved robustness under load.”

The Stone Ridge/Impulse collaboration is an example of hardware/software co-design where the computational resources are optimized for the software problem being addressed. System teams can contact Stone Ridge and Impulse to evaluate this high-throughput, high-data integrity solution for their specific applications.

Developers can purchase Impulse C or Stone Ridge boards from the respective manufacturers. Also, Impulse and Stone Ridge have preconfigured systems available that include all the hardware and software a development team will need to create a first application and connect it up to a datastream. Systems come with 8 hours of remote training and the option of having algorithms professionally refactored for multi-streaming parallelism. On-site training and installation are available.
