【英文介绍】

Trusted TMR processor is a fault-tolerant design based on three-mode redundancy

The (TMR) architecture runs in a lock-step configuration. Figure 1 shows the simplified version

Basic structure of trusted TMR processor module.

The module contains three processor failure containment Zones (FCRS), one for each zone

MOTOROLA Power PC series processors and associated memory (EPROM, DRAM, Flash ROM,

And NVRAM), memory mapped I/O, voter and glue logic circuits. Every processor FCR has it

Two-thirds (2003) read access to the FCR memory of the other two processors

System decontamination operation.

The module's three processors store and execute applications, scans, and updates

Maintain I/O modules and detect system faults. Each processor executes the application

Independent, but synchronized with the other two. One of them should

The processor splits, and other mechanisms allow the resynchronization of failed processors

The other two.

Each processor has an interface consisting of an input selector, difference detection logic,

The memory and output driver bus interface to the intermodule bus. Each output

Processors are connected to different channels through module connectors

Inter-Module bus

The communication between the trusted TMR processor and the modules in the other chassis is through

A trusted interface module, such as a trusted TMR interface to Regent+Plus I/O

Or Expander interface of the Expander chassis.

The functions of the four modular memory types are:

•EPROM - Save the module boot loader

Flash ROM - Storage module firmware and applications

•DRAM - working memory with scalable capacity

NVRAM - holds data such as event logs and retained program data
