Intan Technologies RHD2000 Rhythm FPGA firmware for on-FPGA DAQ (via Open Ephys fork), retargeted from the Opal Kelly XEM6010 (Xilinx Spartan-6 LX45) to the Opal Kelly XEM7310 (Xilinx Artix-7 XC7A200T-1FBG484C).
The Opal Kelly FrontPanel USB layer and DDR2 SDRAM data path have been removed. The RHD2000 SPI acquisition core now streams electrode data directly through a 16-bit word interface, decoupled from any host communication protocol. A processor sandbox module sits on the other end of the stream for on-chip processing.
