FPGA Intellectual Property (IP) Cores
High Performance Front-End Processing in Defense Applications for SDR Platforms
To maximize the processing capabilities of a flexComm™ software defined radio platform,
Spectrum offers field programmable gate array (FPGA) Intellectual Property (IP) cores integrated
onto its platform. The cores offer wide-band capability, good dynamic range and low-level
signal accuracy to fulfill some of the key requirements in defense electronic design. Using off-the-shelf
IP cores enables internal design teams to concentrate on high-level integration issues
and can reduce the cost and development risk relative to designing in-house.
These IP cores are designed using advanced modeling tools that optimize fixed-point
implementations resulting in minimum silicon and least power consumption - particularly
relevant for airborne applications. The cores address broad system issues such as analog to
digital conversion, frequency planning, analog pre-filtering and its overall effect on the digital
receiver performance.
Off-the-shelf cores include:
- Dual 16K point fast Fourier transforms with digital half band filter and 14 bit input
- 32K fast Fourier transforms with sample rates up to 400 MS/s
- Tunable multi-channel receiver cores for high density, small footprint downconversion
- Distributed half-band filters for simultaneously filtering, down-converting and decimating a real input signal
- Fixed-to-floating point converter cores to convert fixed-point data values to single precision floating point format
