Hardware Processing Platform (HPP)

The Hardware Processing Platform (HPP) is 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 includes connections for Ethernet and JTAG to interface to external computers for data transfer and monitoring.
