## KalEdge Platform Guide: An Automated Edge AI Solution Connecting Deep Learning and FPGA

KalEdge is an open-source edge AI development platform designed to address the high barrier to deploying traditional deep learning models on FPGA hardware (requiring mastery of both neural network design and hardware languages). The platform enables automated conversion from Keras models to FPGA synthesis projects via the hls4ml tech stack, offering complete features like model compression, AI-assisted architecture design, and remote hardware synthesis. It bridges algorithm models and hardware implementation, lowering the entry barrier for edge AI.

## Project Background and Core Positioning

KalEdge is developed by the KaleidoForge team, built on the hls4ml open-source project initiated by institutions like CERN, with added automation layers, AI-assisted optimization, and remote hardware synthesis workflows. Its core value lies in eliminating the gap between deep learning model design and FPGA hardware implementation: developers can deploy models to FPGAs without deep mastery of hardware languages like Verilog/VHDL, nor manual handling of timing optimization and resource allocation.

## Core Features

1. **Code-Free HLS Synthesis**: Upload Keras/QKeras models to automatically generate synthesizable C++ Vivado HLS projects, optimizing reuse factors and precision configurations;
2. **AI Architect and Consultant**: Based on the Anthropic Claude large language model (BYOK mode), it provides conversational architecture design suggestions and optimization strategies, helping understand the impact of architecture choices on hardware resources;
3. **Model Compression Suite**: Includes techniques like pruning, Quantization-Aware Training (QAT), Knowledge Distillation (KD), and Low-Rank Decomposition (SVD), supporting combined optimization pipelines (e.g., KD→pruning→QAT) to balance accuracy, memory, and FPGA resources.

## Technical Implementation Details

The tech stack is based on mature open-source tools: model compression uses TensorFlow Model Optimization Toolkit (TF-MOT) and QKeras to implement QAT; hls4ml converts quantized models into HLS C++ code, supporting multiple FPGA boards. The Beta-stage resource estimator can predict board-level resource usage (LUTs, DSPs, FFs, BRAMs) before synthesis, and display comparisons with hardware constraints via radar charts to help evaluate design feasibility.

## Usage Workflow

1. Register an account (optional tiers: Hobbyist/Supporter/Developer/Pro);
2. Upload CSV datasets or use built-in standard datasets like MNIST/CIFAR-10;
3. Supporter and above users configure the AI Architect (unlock conversational design by entering the Anthropic API key);
4. Model training and compression: Establish baseline accuracy, run optimizations like KD, pruning, and quantization;
5. Resource estimation → bit-level precise simulation verification → export HLS project (Pro accounts can use local Build Agent for automatic bitstream synthesis).

## Open-Source License and Business Model

KalEdge uses the Apache License 2.0 open-source agreement; scripts, documents, and tools are open to the community. However, the core KalEdge Cloud Platform SaaS backend, database, and proprietary cloud dashboard are closed-source commercial assets of KaleidoForge. This dual-track model promotes community participation while ensuring commercial sustainability.

## Summary and Outlook

KalEdge is a significant advancement in the tooling of edge AI development. By abstracting complex FPGA deployment processes into visual operations, it greatly lowers the entry barrier for edge AI, providing a complete solution from model to hardware for deep learning models on resource-constrained devices. With future improvements to features like automatic bitstream synthesis, it is expected to become an important infrastructure in the edge AI field.
