Chipen anv\u00e4nder DSP, och huvudprocessorn ARM Cortex styr radioenheten (RF Core) Arm Cortex-M0, som ger huvudprocessorn ett begr\u00e4nsat gr\u00e4nssnitt baserat p\u00e5 meddelande\u00f6verf\u00f6ring. Minnet p\u00e5 radioenheten kan modifieras med hj\u00e4lp av patchar som g\u00f6r det m\u00f6jligt att \u00e4ndra beteendet hos radiosubsystemet. Chipstillverkaren erbjuder moduler f\u00f6r att st\u00f6dja olika tr\u00e5dl\u00f6sa protokoll, implementerade med hj\u00e4lp av dynamiska bibliotek och minnespatchar (liknande de som anv\u00e4nds i Broadcom-chips, som nu \u00e4gs av Cypress). I sin tur styr radioenheten en DSP med en specifik arkitektur. <\/p>\n

Forskarna som presenterade rapporten \u00e5terskapade det propriet\u00e4ra formatet f\u00f6r RF-patchar och demonstrerade hur man f\u00f6rbereder egna patchar f\u00f6r att l\u00e4gga till st\u00f6d f\u00f6r nya tr\u00e5dl\u00f6sa protokoll (till exempel implementeringen av en FM-mottagare), hantering av det tr\u00e5dl\u00f6sa subsystemet och ers\u00e4ttning av firmware. Verktygen f\u00f6r skapande och uppladdning av patchar, samt assemblern f\u00f6r kommandosystemet som anv\u00e4nds i DSP, publicerades under MIT-licensen. F\u00f6r n\u00e4rvarande finns den k\u00e4llkod av firmware som genomf\u00f6r den analoga mottagaren inte i lagret.
