Summary

This blog explains fundamentals of FPGA architecture and the practical reasons embedded engineers might choose one for a product. It walks through how logic blocks, routing, on-chip memory and DSPs differ from CPUs/GPUs and highlights real-world use cases and buying considerations.

Key Takeaways

• Explain the basic building blocks of FPGAs (LUTs, CLBs, routing, BRAM, DSP slices) and how they map to hardware functions.
• Compare FPGAs to CPUs, GPUs, and DSPs to identify when an FPGA delivers unique advantages in latency, parallelism, or deterministic I/O.
• Identify typical embedded use cases (signal processing, custom accelerators, soft processors, deterministic interfaces) where an FPGA is the right choice.
• Estimate integration costs and design workflow impacts, including toolchains, HDL vs HLS trade-offs, and support for soft cores like RISC-V.
• Plan board-level and system considerations such as power, cost, peripheral interfacing, and time-to-market tradeoffs when selecting an FPGA.
