1.1. Kakaretso

The Trusted TMR Processor ke moralo o mamellang liphoso o ipapisitseng le meralo ea Triple Modular Redundant (TMR) e sebetsang ka har'a tlhophiso ea senotlolo. Setšoantšo sa 1 se bontša, ka mantsoe a nolofalitsoeng, sebopeho sa motheo sa Mojule oa Trusted TMR Processor. Mojule o na le libaka tse tharo tsa "Processor fault containment regions" (FCR), e 'ngoe le e 'ngoe e na le "Motorola Power PC series" le memori e amanang le eona (EPROM, DRAM, Flash ROM, le NVRAM), memori e entsoeng ke I / O, voter le glue logic circuits. E 'ngoe le e' ngoe ea processor FCR e voutile batho ba babeli ho ba bararo (2oo3) ho fihlella ho li-memory tse ling tse peli tsa processor's FCR ho felisa ts'ebetso e fapaneng. Li-processor tse tharo tsa module li boloka le ho phethahatsa lenaneo la ts'ebeliso, li hlahloba le ho ntlafatsa li-module tsa I/O le ho bona liphoso tsa sistimi. Mochine o mong le o mong oa processor o etsa lenaneo la ts'ebeliso ka boits'oaro, empa ka khokahano ea lock-step le tse ling tse peli. Haeba e 'ngoe ea li-processor e ka kheloha, mekhoa e meng e lumella processor e hlolehileng hore e hokahane hape le tse ling tse peli.
