SANTA CLARA, Calif. -- October 23, 2012

Renesas Electronics America, a leading supplier of advanced semiconductor
solutions, today announced a robust DSP Library that improves ease of use and
helps speed the implementation of digital signal controller (DSC) designs for
developers working with Renesas’ RX600 and RX200 series of microcontrollers
(MCUs). The new DSP Library provides a robust set of fully optimized and
debugged functions that allow faster implementation of many of the numerical,
filter and transform operations needed in a variety of consumer and industrial
applications, including those for medical, building automation, industrial
automation, sensing and audio.

“Signal conditioning and signal processing are critical in providing the
’intelligence’ required for sensors that play a key role in many of the
emerging technologies enabling the Smart Society, and developers are looking
for new ways to bring differentiated products to market more quickly,” said
Ritesh Tyagi, senior director, Microcontroller Products & Solutions Marketing,
Renesas Electronics America. “The new DSP Library provides the broad base of
functions that developers desire in an easy-to-use format, expanding Renesas’
current development and design tools support for customers designing with our

Featuring more than 300 functions and an easy-to-use, intuitive application
programming interface (API), the new Renesas DSP Library integrates several
functions that enable developers working with the Renesas RX600 and RX200 MCU
devices to reduce development time. For example, instead of writing the filter
code from scratch, developers can simply select one of the filter codes from
the fully optimized and debugged DSP Library, freeing up time and resources to
work on other tasks, such as fine tuning the filter’s response to meet system
requirements. Since you don’t have to do any debug or performance
optimization, development time can be reduced significantly, anywhere from
days to weeks.

In addition to the line up of 308 functions, the DSP Library supports rich
data types, including 16-bit fixed point, complex 16-bit fixed point, 32-bit
fixed point, complex 32-bit fixed point, 32-bit floating point, and complex
32-bit floating point, and offers fine grain options such as scaling options
for the Fast Fourier Transform (FFT).

Pricing and Availability

The DSP Library is available now and can be downloaded free of charge from the
Renesas website at The
current library supports the High-Performance Embedded Workshop (HEW) and the
Renesas RXC compiler. Future versions of the library will also add support for
GCC, IAR, and e^2studio tool chains, and will be supported by a web-based
filter design utility.

Renesas Electronics America will highlight technologies that are enabling a
Smart Society at the Renesas Electronics DevCon 2012 being held in Orange
County, Calif., October 22-25. For the latest Renesas DevCon details and
