7 Ways Your MCU Can Talk to FPGA : On Shrike

7 Ways Your MCU Can Talk to FPGA on Shrike

External Article

This article was originally published at Vicharak.

It walks through multiple communication interfaces between an MCU and FPGA on the Shrike platform, comparing tradeoffs across complexity, performance, and use cases.

Why this matters

MCU–FPGA communication is often treated as a glue problem, but it directly impacts system architecture, latency, and scalability. The choices here define how flexible or constrained your design becomes later.

My context

This comes from practical work around Shrike, where different communication paths were evaluated depending on bandwidth, control requirements, and system constraints.

What’s not obvious at first

Not all interfaces scale the same way. Some are easy to bring up but become bottlenecks quickly, especially when moving from control-plane communication to data-plane workloads.
