T8110B ICS TRIPLEX Trusted TMR Processor Module

Description:

The T8110B Trusted TMR Processor requires no hardware configuration. Every Trusted System requires a System.INI configuration file. Details of how to design this are given in PD-T8082 (Trusted Toolset Suite). The configuration has a Processor assigned to the left slot of the Processor chassis by default. The System Configurator allows the selection of options on ports, IRIG and system functions. The use of the System Configurator is described in PD-T8082. The options are described below.

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 simplified terms, the basic structure of the Trusted TMR Processor module.

The module contains three Processor fault containment regions (FCR), each containing a Motorola 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 has voted two-out-of-three (2oo3) read access to the other two Processor’s FCR memory systems to eliminate divergent operation.

The module’s three Processors store and execute the application program, scan and update the I/O modules and detect system faults. Each Processor executes the application program independently, but in lock-step synchronisation with the other two. Should one of the Processors diverge, additional mechanisms allow the failed Processor to re-synchronise with the 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 each Processor is connected by the module connector to a different channel of the triplicated Inter-Module Bus.
