High-Rate Data Input using the Tilera Multicore Processor

Completed Technology Project

Project Description

Gb/s Ethernet Input

Solve the existing problem of handling the on-board, real time, memory intensive processing of the Gb/s data stream of the scientific instrument.  Investigate the COTS Tilera multicore embedded processing systems' methods of I/O focusing on the high rate Ethernet methods.  

Define the software data processing methods needed to support the short-term and long-term development of the scientific instrument.   This proposal will investigate standard Ethernet I/O methods to be compared with Tilera specific Ethernet methods of I/O, including the high rate Ethernet method that uses Tilera's multicore Programmable Intelligent Packet Engine (mPIPE) system.

Develop software to process data stream input over the Ethernet using standard TCP/IP protocols, Ethernet using Tilera's Zero Overhead Linux, and Ethernet using the Tilera mPIPE packet processing system.   Develop and compare the different data input methods including data processing speed, level of programming effort, level of hardware or external setup, ease of understanding, and ease of execution.
