Actel's high configurable DSP IP
cores expand its RTAX-DSP FPGAs
Actel has announced the expansion of its RTAX2000D and
RTAX4000D DSP FPGAs with new configurable DSP IP cores.
The new cores create common DSP functions such as filters
(FIR, IIR) and transforms (FFT, IFT, DCT). Using a graphical
user interface (GUI) embedded in Actel's Libero Integrated
Design Environment (IDE), and targeting RTAX-DSP space-flight
FPGAs.
"By providing a simple but powerful user interface,
these configurable DSP cores greatly simplify and shorten
the design cycle for DSP applications targeting our new
RTAX-DSP FPGAs for space-flight applications," said
Ken O'Neill director, high reliability product marketing
at Actel. "These new offerings expand the horizons
of the RTAX series of FPGAs, which already have a well-established
space-flight track record."
The three new DSP IP cores multiplier, multiplier with
adder or subtractor, multiplier with accumulator, which
are supported through software dialog windows allowing for
the quick selection and configuration of multiple common
DSP functions.
The configurable DSP IP cores generate structural netlists
in either Verilog or VHDL and can be easily instantiated
into a complex RTAX-DSP FPGA design using Actel's Libero
IDE and SmartDesign graphical block system design creation
tool. Comprehensive handbooks are available to assist designers
in building various DSP functions.
The IP cores take advantage of the embedded mathblocks
available in RTAX-DSP devices. Each mathblock contains a
18x18 bit hardware multiplier, plus a 41-bit internal adder-subtractor
and register that can be configured for accumulating multiplier
results. The multiplier can be broken into two 9x9 multipliers
when less precision and more multipliers are needed. A number
of different pipelining options are available, with optional
registers on all inputs and outputs. Mathblocks have cascade
outputs and inputs for common applications like FIR filters,
they may be chained for maximum performance, leaving FPGA
fabric resources free. RTAX-DSP devices have up to 120 mathblocks,
each of which can perform full-precision multiplications
at up to 125 MHz and has built-in protection against radiation-induced
single event upsets (SEU) and single event transients (SET).
Price: At $2495 per seat
Availability: The cores are available immediately and are
included with an Actel Libero IDE Platinum software license
Node-locked and floating licenses are available.
