[Verse 1] When you're coding with just kilobytes to spare Every pointer and variable needs your care Stack grows upward, heap shrinks down Memory pressure all around Choose your data structures wise Arrays packed, no wasted bytes Structs aligned to boundaries clean Tightest footprint ever seen [Chorus] Optimize, minimize, every single bit Pack it tight, get it right, make the pieces fit Static first, dynamic last, plan before you code Compile time, save the RAM, lighten up the load Optimize, minimize, that's the memory way Pack it tight, get it right, every single day [Verse 2] Unions share their memory space One field active, saves the place Bit fields pack the flags together Boolean storms you'll weather better Register keywords hint the compiler Make your hottest loops much quicker Inline functions save the stack No more call and callback track [Chorus] Optimize, minimize, every single bit Pack it tight, get it right, make the pieces fit Static first, dynamic last, plan before you code Compile time, save the RAM, lighten up the load Optimize, minimize, that's the memory way Pack it tight, get it right, every single day [Bridge] Pool your allocations, batch them up in blocks Garbage collection's luxury that embedded code just mocks String literals in ROM, constants never change Stack allocation's fastest but its lifetime's got a range [Verse 3] Preprocessor macros expand at build time Template specialization, optimized design Dead code elimination strips the unused parts Profile guided optimization's where the real magic starts Zero cost abstractions give you both worlds clean High level thinking with a low level machine [Chorus] Optimize, minimize, every single bit Pack it tight, get it right, make the pieces fit Static first, dynamic last, plan before you code Compile time, save the RAM, lighten up the load Optimize, minimize, that's the memory way Pack it tight, get it right, every single day [Outro] When kilobytes are all you've got Make every single byte count Memory optimization That's what systems engineering's about
