Introduction

System architecture

Overview

CORSIGHT is a complete embedded PC system built around intel Atom processor (Atom E3845 1.91GHz, CORSIGHT II) and (Atom E3940 1.6 GHz, CORSIGHT III) of the intel embedded roadmap. Any of the wide choice of NET’s sensors may be used in CORSIGHT.  The PC offers LAN/WLAN, DP++ as well as USB 2.0 interface. Different boot and storage media exist.

Sensor data is acquired and possibly preprocessed using an FPGA based subsystem. The pre-processing options include, input look-up-table, format conversion, and buffering, before the data is transferred to the main PC using the high performance PCI-Express DMA transfer. General purpose I/O's (optocoupler & TTL inputs and outputs, RS232 interface) enable the control of external devices.
