Fixed Point FFT

Abaco Systems' fixed point FFT cores are the most efficient and fastest available in the FPGA world. With a revolutionary architecture for efficient memory usage and balanced use of arithmetic and logic resources, we offer complete FFT solutions with any input resolution up to 2Gsps. Whether you require a forward FFT, Inverse FFT, a 2D FFT, correlation or any algorithm efficiently performed with a Fourier transform, our technology will offer you the best solution for a cost-effective implementation. Smart IP solutions increase board efficiency and reduce the price of digital signal processing systems. StellarIP is available for this product, whih delivers a simple way to design FPGA firmware with automated code and bitstream generation.


Floating Point FFT

Abaco Systems' Floating Point FFT core is the most flexible IEEE-754 compliant FFT core available in the FPGA world. Designed for high performance programmable devices from Xilinx and Altera, this core performs Fast Fourier Transforms ranging from 256 points to 64M points and is ideal for high precision spectral analysis, radar and video processing applications.

Abaco Systems' Serial Front Panel Data Port (sFPDP) IP core for FPGAs is based on the ANSI/VITA 17.1-2003 standard. The 4DSP sFPDP IP core is a serial communication protocol designed to provide low latency and high transfer rates. Real-time applications benefit from the high performance and low overhead built into the core. This intellectual property core can be implemented on any Xilinx FPGA family and is rated for transfer speeds of up to 5Gbps data rates. The use of fiber optic cables allows sFPDP to operate over long distances (up to 10KM).

The heart of the sFPFP core lies within the sFPDP transceiver module which takes care of encoding and decoding the sFPDP packets. The sFPDP protocol allows connectivity directly to the transmit input and output of a Xilinx MGT or GTP.

This protocol is available pre-ported to a number of PMC - XMC boards as a turnkey, plug-n-play solution for any PMC - XMC host motherboard. 4DSP’s intuitive StellarIP FPGA development tool is available for this product. It offers a simple way to design FPGA firmware with automated code and bitstream generation.

Wideband Digital Down Converter

A Digital Down Converter performs channel access functions in digital receivers. It is used for extracting a channel (frequency band) of interest in a wideband signal. Abaco Systems' wideband DDC core employs a quad DDC architecture to achieve ultra high performances. The core accepts up to 16-bit complex data and can process 1GSPS continuously. With a fully programmable architecture at all stages of the processing, this core combines flexibility and speed and can be used in combination with our dual-channel 1GSPS ADC module.

Input stage

Four 16-bit complex samples can be loaded to the core in parallel at a rate of 250MHz, thus providing an input bandwidth of 1GSPS. The input gain, implemented using multipliers, is user programmable.
