Bit by Bit Signal Processing

A business designing and supporting IP for signal processing applications, including one of the world's best high-speed Fast Fourier Transforms (FFTs).

"BxBFFT" Fast Fourier Transform

The BxBFFT is an amazing high-speed streaming FFT. It's now at version 5.0, and supports Xilinx and Altera FPGAs. It has multiple industrial, academic, and military customers. Some of its advantages:

1. Power savings:
Half the power of other FFTs (in Xilinx).

2. Resource savings:
Half the FPGA LUTs (in Xilinx).

3. High Throughput:
Highly parallel processing at the highest clock rates. Also the lowest latency.

4. Large FFT Sizes:
Supports 128k and greater FFT sizes with efficiency.

5. Feature Support:
Non-power-of-2 FFTs, real-to-complex FFTs, many included options to meet design goals.

6. Productivity:
Easier to get reliable results; Faster synthesis and simulation.

7. Vendor Independence:
Efficient support of multiple FPGA vendors, with a path to ASICs.

The BxBFFT is well-suited for digital signal processing applications where the sample rate is many times the FPGA clock rate, such as cellular backhaul, radar systems, spectral switches, high-bandwidth beamformers, radio telescopes, test and measurement systems, analog system simulators, high-speed radios, and communication satellites. For more information, including features, performance, and pricing, see the BxBFFT product page and the additional pages that it references.

BxBApp

This Spectrum Analyzer, Oscilloscope, and Network Analyzer application demonstrates the BxBFFT in operation. It shows the BxBFFT operating flawlessly at real time rates on 5GHz bandwidths, with processing noise below the noise floor, at more than 100dBFS down. It's also a useful application in its own right. For more details, see the BxBApp product page.

Channelizer Tutorial

Bit by Bit Signal Processing is happy to provide a tutorial on derivation of the Polyphase Filter Bank (PFB) Channelizer. This may help advanced customers understand how to use and analyze Bit by Bit's upcoming channelizer product. Alternately, channelizer consulting is available. The tutorial is available on the Tutorials page.

About Bit by Bit Signal Processing

Bit by Bit Signal Processing was founded by Ross Martin in 2018, after a career designing hardware and algorithms for processing data for radar systems, optical imaging systems, and satellite communication systems. The business supplies Intellectual Property supporting these applications.
