Freaking computers, how do they work?

" summary

Shows exactly how high-level code becomes CPU work: assembly for x86 32-bit, register layout and stack behavior, and concrete demos. Compares a looped “dumb” multiply (~28 instruction cycles) to the CPU imul (one instruction, one cycle), calls assembly from C, exposes the native DLL to C# via P/Invoke, and triggers it from JavaScript through a small web server. Proves the path by changing assembly (adds 1000) and rebuilding to show the running code. EAX/EBX/ECX/EDX
