Previously: <a href="https://dean.sellers.id.au/2026/10/19/riscv-10-what-does-a-multiply-cost/">What does a multiply cost?</a>.</em></p> <p>The point of this project was never only to build a CPU. It was to build one, make it run real code, and <strong>find out where it breaks</strong>. This post is that list. Some of the edges are bugs I found, and each of those has a story about how. Some are limits of the design, and they say what to build next. And one of them is bigger than all the others, and I will start there.</p>
