Highly Parallel, Fast Memory, Peripheral Access for RISC-V Many-Core Processors

LeWiz research from NASA Phase 1 I-Corps program showed verystrong interest in LeWiz solutions from NASA telescope team, DoD lab and commercial storage customers with potential for immediate revenue. Previously, LeWiz developed fault-tolerant (FT) 1) high performance network-on-chip bus (NOC) for multi-channel access supporting High Bandwidth Memory controller and/or high speed peripherals, and 2) 64-bit, 6-stage RISC-V CPU core with NOC interface capable up to 500K cores in a system. This Phase 2 proposed to further develop the Phase 1solutions to meet the immediate customer requirements and productize the solutions for infusion intoNASA and commercial customer products. 2 subsystems would be developed i) spectrometer memory/peripheral subsystem with highly parallelized access channels supportingDDR4 memory, 100Gbps Ethernet, multiple digital-to-analog converters, ii) RISC-V processor with enhanced NOC router integrated to the highly parallel NOC/HBM controller. The solution would also meet NASA SBIR Z2.02 Topic requirements for A fault-tolerant RISC-V processor IP core ...that is augmented to provide data parallelism, which is needed to accelerate image processing and science data processing. andenablingfuture development of accelerators and co-processors for many-core high-performance processingarchitecture advancing state of the art FT processors for space flights and autonomous applications. No other known solution is as advanced as the proposed for space applications. The project will be carried outover 2 years in the US.

NASA applications include flight control, landing control, instrumentations, payloads, sensors, navigation systems, networking, scientific processing, image processing, communication sub-systems for satellites, space stations, vehicles, space habitats. Very strong interest from NASA Microwave Kinetic Inductance Detector Team for space telescope applications inspectrometer (Origin Space Telescope) and RF-submillimeter (SELFI) programs

This is early/mid-stage (TRL 3) — 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.
