Con Blink, se pueden ejecutar programas Linux compilados para la arquitectura x86-64 en otros sistemas operativos compatibles con POSIX (macOS, FreeBSD, NetBSD, OpenBSD, Cygwin) y en hardware con arquitecturas diferentes (x86, ARM, RISC-V, MIPS, PowerPC, s390x). El c\u00f3digo del proyecto est\u00e1 escrito en C (ANSI C11) y se distribuye bajo la licencia ISC. Solo se requiere libc (POSIX.1-2017) como dependencia.        <\/p>\n<p>En t\u00e9rminos de funcionalidad, Blink se asemeja al comando qemu-x86_64, pero se distingue de QEMU por su ejecuci\u00f3n m\u00e1s compacta y un aumento significativo en el rendimiento. Por ejemplo, el archivo ejecutable de Blink ocupa solo 221 KB (en una versi\u00f3n reducida \u2014 115 KB) en lugar de 4 MB del qemu-x86_64, y en cuanto a rendimiento, en algunas pruebas, como la ejecuci\u00f3n en el emulador GCC y la realizaci\u00f3n de operaciones matem\u00e1ticas, supera a QEMU aproximadamente por el doble.       <\/p>\n<p>Para garantizar un alto rendimiento se utiliza un compilador JIT, que convierte sobre la marcha las instrucciones fuente en c\u00f3digo de m\u00e1quina para la plataforma de destino. Se admite la ejecuci\u00f3n directa en el emulador de archivos ejecutables en formatos ELF, PE (Ejecutables Portables) y bin (ejecutables planos), compilados con las bibliotecas est\u00e1ndar de C como Cosmopolitan, Glibc y Musl. Se ha implementado soporte incorporado para 180 llamadas al sistema de Linux y emulaci\u00f3n de aproximadamente 600 instrucciones del procesador x86, abarcando los conjuntos de instrucciones i8086, i386, SSE2, x86_64, SSE3, SSSE3, CLMUL, POPCNT, ADX, BMI2 (MULX, PDEP, PEXT), X87, RDRND, RDSEED y RDTSCP.    <\/p>\n<p>Adem\u00e1s, se est\u00e1 desarrollando una utilidad basada en Blink llamada blinkenlights, que proporciona una interfaz para visualizar el progreso de la ejecuci\u00f3n del programa y analizar el contenido de la memoria. Esta utilidad puede utilizarse como depurador, admitiendo el modo de depuraci\u00f3n inversa (Reverse-Debugging), que permite retroceder en la historia de ejecuci\u00f3n y regresar a puntos ya ejecutados anteriormente. El proyecto es desarrollado por el autor de desarrollos como la biblioteca C Cosmopolitan, el puerto del mecanismo de aislamiento pledge para Linux y el sistema de ejecutables universales Redbean.
