IP Cores, Inc. Announces three low-latency Fast Fourier Transform IP cores for SoC applications in the OFDM-based communications (WiMAX, MBOA, IEEE 802.11) and GPS fields

FFT64 core and two versions of FFT1024 are very compact and provide parameterized bit width with throughput of 1 sample per clock

Palo Alto, California, June 19, 2007 -- IP Cores, Inc., expanding its portfolio beyond security IP cores, today announced three compact FFT IP cores to support OFDM-based communication standards like WiMAX, MBOA, IEEE 802.11. New FFT1024-4, FFT1024-8, and FFT64 IP cores enable System on Chip (SoC) vendors to design extremely compact OFDM modems.

"Addition of the FFT cores to our portfolio permits us to broaden our customer base," said Dmitri Varsanofiev, CTO of IP Cores. "The FFT cores offered by IP Cores, Inc. are extremely efficient and flexible. Their compact sizes are especially useful in WiMAX MIMO applications."

OFDM-Based Communication Standards

Practically every modern communication standard – from IEEE 802.11 wireless networks to satellite communications - relies on the orthogonal frequency division multiplexing (OFDM) technology.  Transmission and reception of data using the OFDM modulation requires an implementation of the Fast Fourier Transform (FFT) and inverse FFT (IFFT) in the modem.

FFT1024 configurations support either a 1024 point complex FFT, IFFT or two 512 point simultaneous transforms, which is a useful feature for supporting the IEEE 802.16e (WiMAX) standard. Gate count for a fully self-contained 10-bit FFT1024-4 starts at 50K gates (the core also uses 40 Kbits of memory). FFT1024 is capable of processing one sample per clock at frequencies up to 250 MHz in the 90 nm ASIC process and 80 MHz in an FPGA. The latency of the FFT1024-8 is 420 clocks, while the smaller FFT1024-4 has a latency of 1260 clocks.

FFT64 core delivers the 64 point complex FFT used in IEEE 802.11 standard and GPS applications.

Cores are available in multiple configurations to meet specific SoC throughput, power, and gate count goals. For more information about IP Cores’ product line, please visit www.ipcores.com.
