Completed TRL 2 (started at 2, targeting 3)
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.
The results from this IRAD will support the ongoing development of the scientific instrumentation.
Increase the capabilities of on-board data processing, including ingest and processing of high data rates that will be done on-board in the future.
This work can benefit any space-based instrument that would require high performance onboard data processing.

Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
