Description

The Trusted TMR Processor is a fault tolerant design based on a Triple Modular Redundant(TMR) architecture operating in a lock-step configuration. Figure 1 shows, in simplifiedterms, the basic structure of the Trusted TMR Processor module.The module contains three Processor fault containment regions (FCR), each containing aMotorola Power PC series Processor and its associated memory (EPROM, DRAM, Flash ROM,and NVRAM), memory mapped I/O, voter and glue logic circuits. Each Processor FCR hasvoted two-out-of-three (2oo3) read access to the other two Processor’s FCR memorysystems to eliminate divergent operation.The module’s three Processors store and execute the application program, scan and updatethe I/O modules and detect system faults. Each Processor executes the application programindependently, but in lock-step synchronisation with the other two. Should one of theProcessors diverge, additional mechanisms allow the failed Processor to re-synchronise withthe other two.Each Processor has an interface which consists of an input voter, discrepancy detector logic,memory, and an output driver bus interface to the Inter-Module Bus. The output of eachProcessor is connected by the module connector to a different channel of the triplicatedInter-Module Bus.
