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
- FreeLynx 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.
