In this post, I explore ways to improve interrupt latency and jitter on the BoxLambda SoC.

In this post, I remove more functionality than I’m adding, and the BoxLambda SoC becomes a lot simpler and faster as a result. I’ll also briefly describe how the RISC-V GNU toolchain for BoxLambda is built.

First post on Bluesky. I maintain an open-source project called BoxLambda. BoxLambda creates a retro-style FPGA-based microcomputer from open-source components. The microcomputer serves as a platform for both software and RTL experimentation.
