Actel Corp. has introduced a
finite impulse response (FIR) IP core generator
optimized for use with the company's flash- and
antifuse-based families of FPGAs.
CoreFIR, the latest addition to Actel's DirectCore
portfolio, is an easy-to-use filter generator that
uses a distributed arithmetic implementation
methodology to create FPGA-based low- and high-pass
digital filters for a variety of general signal
filtering, detection and analysis functions.
Designed for lower sampling rates, Actel said, the IP
core generator can be implemented in its smallest FPGA
devices and provides a level of flexibility and
cost-effectiveness that is more attractive than
standard processor or ASIC alternatives. CoreFIR
generates filters to detect and analyze signals for
applications such as radar, sonar, ultrasound and
others in the communication, space, medical,
industrial and military markets.
"With programmable logic becoming an attractive
alternative to standard DSP processors, CoreFIR offers
designers an easy and cost-effective way to implement
DSP functionality," shared Yankin Tanurhan,
senior director of applications and IP solutions at
Actel. "Using the high-performance, highly
efficient and easy-to-use core generator, designers
can implement digital filters that are customized for
their application and reduce development time from
weeks to days."
CoreFIR, designed for Actel's Axcelerator, RTAX-S, SX-A
and ProASICPLUS FPGAs, can create FIR
filters that operate at more than 160MHz when
implemented on the company's antifuse-based
Axcelerator devices. Unlike standard DSP solutions,
CoreFIR is designed to be small and highly
customizable, Actel added. Using the core generator,
designers can input the number of taps, bit width and
coefficient bit width, and the ratio between system
clock frequency and data sampling rate for a variety
of configurations, including signed or unsigned
inputs, fixed or variable coefficients, and embedded
RAM. In addition, the core generator outputs RTL code
and a testbench, enabling the designer to verify the
specified design configuration.
The new generator is already available, with pricing
starting at $500. In addition, a free evaluation
version is available for download via the company's website.
