Hardware Processing Platform

(HPP v1.0.0). A closed loop signal processing platform that connects directly to the Digital Lynx SX motherboard, providing real-time data analysis and response for low-latency feedback stimulation experiments.

With HPP, you can now analyze and respond to input signals in less than 1 millisecond!

HPP can execute experiment stimuli with precise control of Digital Lynx SX analog and digital outputs. HPP contains a customizable processor that communicates with the DLSX motherboard, providing low-latency access to the input acquisition data – both the analog data and the TTL I/O.


  • User-programmable; customize to any application
  • Sub-millisecond latency feedback response
  • Digital signal filtering and other DSP functions
  • Analog signal output
  • Allows combination of detect and trigger to manage complex closed loop experiments

Process data from all digital and analog Digital Lynx SX inputs, including:

  • Buffered tethered headstages / Digital Lynx input boards
  • FreeLynx wireless digital telemetry headstages
  • Digital multiplexing (MUX) headstages
