Hardware Processing Platform (HPP)

A low-latency 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, researchers can 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 DL-SX motherboard, providing low-latency access to the input acquisition data - both the analog data and the TTL I/O. Process data from all Digital Lynx SX inputs, including:

  • Buffered tethered headstages / Digital Lynx input boards
  • Cube2 wireless digital telemetry headstages
  • Digital multiplexing (MUX) headstages

Example Applications

  • Spike detection and classification
  • Neural ensemble detection and burst analysis
  • Low frequency narrow band signal response (ie., Alpha, Theta, Gamma)
  • Digital signal filtering and other DSP functions
  • Experiment control
  • Analog signal output
  • Complex stimulation
  • Precision TTL pulse trains

NOTE: Currently requires advanced programming skills.


  • Integrates with Digital Lynx SX for access to all signals for real-time data processing

  • Unprecedented processing speed: sub-millisecond latency

  • Upgrade existing Digital Lynx SX systems

  • Eliminates operating system latencies – deterministic response

  • USB connection for external device interfaces

  • Oscillation detection – narrow band low frequency

  • Stimulate with Digital Lynx SX analog and digital outputs

  • Ethernet and JTAG available to interface to external computers for data transfer and monitoring
