Your computer doesn’t “think” — it calculates. Inside every CPU is something called an ALU (Arithmetic Logic Unit). That’s where the real work happens. Every tap, every scroll, every game— breaks down into tiny math and logic operations. Addition. Comparison. Decisions.

PicoRV32 is what happens when CPU design stops trying to look pretty and starts trying to win. It’s a tiny open-source RISC-V core, written in Verilog, built for one thing: doing more with less. No flashy giant pipeline. No bloated architecture diagrams. Just a brutally

This single diagram explains how EVERY CPU works. Most people memorize instructions. Very few understand execution. If you get this, you understand: • RISC-V • Pipelines • Performance Let’s break it down 🧵👇

The 5-stage CPU lifecycle: Fetch → Decode → Execute → Memory → Writeback 👇

The most important register in a CPU isn’t what you think. It’s the Program Counter (PC). It literally controls what your program does next. If you understand this, you understand execution. The PC stores ONE thing: 👉 Address of the next instruction Every cycle: PC →

Most people think the CPU was invented once. It wasn’t. In a way, the CPU has been reinvented at least 5 times over the last 50 years: 1971 — Intel 4004 The first commercial microprocessor. A calculator chip project accidentally created the modern CPU. 1980s — RISC

The 50-year war between CISC and RISC has a funny ending: Neither side really won. Because both sides changed. In the 1980s, RISC looked like the future: - simpler instructions - cleaner pipelines - better theoretical performance Meanwhile x86 looked doomed: - messy
