FPGA SoC for Custom Flight Controller

Hello everyone,

I’m currently working on developing a custom flight controller for small unmanned helicopters, and I’d like some advice on selecting the right SoC FPGA for the project. Here’s a quick overview of the requirements:

• Board Size: ~40x40 mm
• Processor: Dual ARM Cortex (preferably A9, A53, or higher)
• OS: Linux-based, capable of running Ardupilot, PX4, and Mission Planner
• Tasks: Real-time control, image processing, machine learning, and VSLAM
• Power Efficiency: Optimized for UAV applications
• Budget: The FPGA chip should cost between $150-$200 maximum

I'm looking for a price-optimized FPGA that can handle vision and ML tasks while ensuring stable real-time control. Key priorities include sufficient logic cells, high-speed I/O interfaces, and compatibility with open-source autopilot systems.

Does anyone have suggestions on specific FPGA chips Altera that fit these criteria? I’d appreciate any recommendations and insights from those with experience in similar projects.

Thanks in advance for your help!
