05_27_IMPLEMENTATIONS - El Corazn Ejecutable de AudioLab¶

< RESUMEN EJECUTIVO¶

IMPLEMENTATIONS es el repositorio de cdigo C++ que contiene TODAS las implementaciones ejecutables del sistema AudioLab. Es el corazn pulsante donde las especificaciones abstractas y los blueprints arquitectnicos se materializan en DSP real, ejecutable, optimizado y listo para produccin.

Por qu existe?¶

Sin este subsistema, AudioLab sera puro vapor: documentos, planes, especificaciones, pero cero capacidad de procesar audio. Este es el mdulo que REALMENTE ejecuta en los CPUs, GPUs, y DSPs del mundo real. Todo lo dems en el proyecto existe para SOPORTAR este cdigo.

Posicin en el Sistema (Subsistema #27)¶

Se configura DESPUS de todos los subsistemas de diseo (00-26) porque necesita consumir: - Algorithm Specs (03) - Reference Implementations (15) - Performance Variants (16) - Quality Metrics (18) - Fabrication Tools (20) para cdigo generado

Es el SUBSISTEMA MS CRTICO del proyecto completo. Su ausencia invalida todo lo dems.
