[Verse 1] Deep inside the CPU's heart, registers wait in silence EAX accumulates the math, while EBX holds our guidance ECX counts down every loop, EDX extends precision ESP guards the stack's top, EBP frames our vision [Chorus] Move the data, shift and store Direct addressing knocks the door Indirect pointers chase the trail Indexed arrays never fail Registers dance with memory's call Base plus offset, scaling all From cache to RAM, the journey flows That's how the silicon river grows [Verse 2] Immediate values hardcoded fast, constants locked in stone Register mode keeps data close, no trips to memory's zone But when we need dynamic space, displacement shows the way Bracket notation finds the spot where variables can stay [Chorus] Move the data, shift and store Direct addressing knocks the door Indirect pointers chase the trail Indexed arrays never fail Registers dance with memory's call Base plus offset, scaling all From cache to RAM, the journey flows That's how the silicon river grows [Bridge] Scale factor multiplies the stride Two, four, eight bytes side by side SIB encoding tells the tale Source index base will never fail Effective address calculated clean The fastest path you've ever seen [Verse 3] Load effective address tricks the mind, arithmetic disguised No memory access, just the math, efficiency surprised Segment registers hold domains, code and data split apart Stack segment guards the function calls, close to processor's heart [Chorus] Move the data, shift and store Direct addressing knocks the door Indirect pointers chase the trail Indexed arrays never fail Registers dance with memory's call Base plus offset, scaling all From cache to RAM, the journey flows That's how the silicon river grows [Outro] Thirty-two bits of blazing speed Sixty-four when power's the need Registers reign, memory serves In silicon's electric curves
