El transmisor anal\u00f3gico puede no ser realizable \u2014 los chips son puramente digitales.     <\/p>\n<p>Los chips utilizan DSP, y el n\u00facleo principal ARM Cortex gestiona el n\u00facleo de radio (RF Core) Arm Cortex-M0, que proporciona al n\u00facleo principal una interfaz limitada basada en la transmisi\u00f3n de mensajes. La memoria del n\u00facleo de radio se puede modificar mediante parches que permiten cambiar el comportamiento de la subsistema de radio. El fabricante de los chips ofrece m\u00f3dulos para soportar diferentes protocolos inal\u00e1mbricos, implementados utilizando bibliotecas din\u00e1micas y parches de memoria (similares a los utilizados en los chips de Broadcom, que ahora son propiedad de Cypress). A su vez, el n\u00facleo de radio gestiona un DSP de arquitectura espec\u00edfica.       <\/p>\n<p>Los investigadores que presentaron el informe recrearon el formato propietario de parches RF y demostraron c\u00f3mo preparar sus propios parches para a\u00f1adir soporte a nuevos protocolos inal\u00e1mbricos (por ejemplo, implementaron un receptor de FM), gestionar la subsistema inal\u00e1mbrica y reemplazar el firmware. Las herramientas para crear y cargar parches, as\u00ed como el ensamblador para el sistema de comandos utilizado en DSP, se han publicado bajo la licencia MIT.
