This repository will contain the VHDL sources and helper scripts, PCB design files, and photographs.
## Current status: All 3 firmwares synthesized and built.
Line mode succesfully verified against version compiled on earlier toolchain
## Current status: All 3 firmwares synthesized and built. Created a new SDR personality.
All firmwares now tested succesfully in operation.
### Specifications:
* 70 MS/s, real

* Line mode: 2048 spectral bins, 267 spectra/second
* Raw mode: unprocessed 70MS/s 10bit, 700Mb/s output
* SDR mode, 5MHz: 5MHz of bandwidth centered around 21.4 MHz, 16bit IQ, GnuRadio compatible

### Requirements:
* Xilinx ISE 14.7 (WebPack)
* Ubuntu 16.04 LTS
* Ubuntu 16.04 LTS (likely to work on any Linux with ISE)
* Make (project is controlled through a Makefile, not ISE)
### TODO:
* Convert all firmwares to use 1Gb/s Ethernet
* Update and merge current firmwares, single Makefile, code re-use
* Add WOLA to the FFT-based backends
* SDR firmware: use CIC + compensating FIR for flatter passband with less resource usage
* New firmwares:
* Digital Down Converter (DDC) for use with GnuRadio and SETI@home
* GPS cross correlation or squaring receiver (for cross-scans)
* Run from 10MHz clock instead of 140 MHz
* Absolute time or PPS input
