Correlator v3.1

The new correlator (version 3.1) is under way, and I thought I’d share some progress…

Features:

  1. Combines the Spartan 6 FPGA and RAM for the raw data buffer
  2. Single SODIMM correlator board.
  3. Same features as the existing correlator board (based on a Papilio Pro clone).

The first prototype has been assembled

The new correlator is the smaller board with all the debug wires connected. An old correlator board is above it.

and a few bugs have been ironed out. We now have a prototype being tested on nz-elec. It will require another round of prototype hardware, but it is looking good for being part of the next development kit.

Correlator v3.1 second prototype has arrived and so far, no manual fixes are needed! I’ll attach some photos :slight_smile:
