A reproducible deployment kit that supports running Gemma model inference on the Xilinx KV260 FPGA development board, targeting deterministic edge AI application scenarios.
Section 01
This project provides a reproducible deployment kit for running Google's Gemma models on Xilinx KV260 FPGA development board, focusing on deterministic edge AI applications. It leverages FPGA's advantages (low power, deterministic latency, customization) to address edge deployment challenges of large language models (LLMs), offering a production-ready solution beyond technical demonstration.
Section 02
The demand for deploying LLMs on edge devices grows rapidly, but traditional CPU/GPU struggle with power consumption, latency, and determinism. FPGA (Field-Programmable Gate Array) as reconfigurable hardware offers unique benefits: low power, deterministic delay, and high customization. Gemma4-on-FPGA is a complete deployment solution for KV260, enabling deterministic edge AI applications.
Section 03
Xilinx KV260: Zynq UltraScale+ MPSoC (4-core ARM Cortex-A53 + 2-core Cortex-R5F + Mali-400 GPU), 4GB DDR4, industrial temperature range support, fanless option, containerization deployment support. Gemma Model: Open-weight series (2B/7B params) based on Gemini tech, safe, commercial-friendly, efficient for edge (small size, community toolchain support).
Section 04
Architecture: Reproducibility (version-locked dependencies, one-click automation scripts, detailed docs); system components (quantization/pruning/knowledge distillation, Vitis AI-based FPGA implementation, PetaLinux runtime). Process: Env prep (hardware/software/model acquisition), model compilation (quant calibration, conversion to Vitis AI format, DPU binary generation), system deployment (image build, app/model deployment, performance validation).
Section 05
Determinism: Predictable behavior (same input → same output, fixed latency) vs CPU/GPU's jitter from OS scheduling/cache. Key Scenarios: Industrial automation (robot control, quality inspection), autonomous driving (decision systems), medical imaging (surgery navigation), financial trading (high-frequency). Application Cases: Smart edge gateway, embedded dialogue system, real-time content audit, edge knowledge base QA.
Section 06
Performance Metrics: Latency (tens-hundreds ms), power (10-30W), determinism (jitter <5%), resource utilization. Challenges & Solutions: Resource constraints (INT8/INT4 quantization, sparsity, chunked loading); memory bandwidth (data reuse, on-chip cache); development complexity (Vitis AI HLS, pre-optimized DPU IP).
Section 07
Limitations: Model size (2B only on KV260), FPGA development threshold, limited ecosystem vs CUDA. Future: Larger models on advanced FPGAs, smarter automation tools, heterogeneous computing (CPU/GPU/FPGA), standardized edge AI interfaces.
Section 08
Gemma4-on-FPGA demonstrates feasible LLM deployment on resource-limited edge devices using KV260 and Vitis AI, offering deterministic, low-power solutions. For latency-sensitive edge AI, FPGA is a strong candidate. As model compression and FPGA toolchains advance, such deployments will become more practical and widespread.

Nornir MCP Server is an enterprise-level server based on the Model Context Protocol (MCP). It seamlessly integrates large language models (such as Claude) with the Nornir network automation framework, supporting natural language orchestration for multi-vendor network devices (Cisco, Arista, Juniper, etc.), and providing production-grade features like a dual-engine architecture (NAPALM + Netmiko), intelligent filtering, and a secure sandbox.
Bibliothèque Française LLM is a structured indexing and annotation project for French public domain literature designed specifically for large language models (LLMs). It integrates multiple authoritative sources such as DraCor, Common Corpus, and Wikisource, providing metadata indexing categorized by genre, author, and era, as well as in-depth annotations for dramatic texts (including characters, lines, stage directions, etc.). Its aim is to enable LLMs to efficiently read and understand classic French literary works.
