3. Application

3.1. Module Management

The module is configured automatically by the Trusted

TMR Processor.

Configuration information in the module’s memory is compared with the physical I/O sub-system. Any

discrepancies are identified and reported.

Changeover between active and standby modules (in dual module configurations) is controlled by the

Trusted

TMR Processor, when the active Trusted

TMR Interface either fails or is removed

3.2. Communication Busses

3.2.1. Inter-Module Bus

The processor sub-system fault containment regions contain the Bus Interface for the Inter-Module

Bus. The Bus Interface provides communication between modules in the Controller chassis.

The Inter-Module Bus contains the following triplicated signals:

Additionally, a CHASSIS CONNECTION signal is provided for grounding the module electromagnetic

interference shield.

3.2.2. Processor Memory Voting Bus

The memory voting bus is 8 bits wide and provides real-time voting of memory read cycles.

3.2.3. Processor Control Voting Bus

The control voting bus is used to vote the necessary control signals for the Regent+Plus I/O Processor

design.

• 6.5V - IMB power

• DATA - 8 bit, bi-directional bus

• CMND/RESP bus direction control

• IOM_SEL I/O module select signal

• IOM_CLK I/O module clock signal

• SYS_WDOG indicates the operability of the associated TMR Processor

fault containment region

• PWR_FAIL indicates a power fault in the associated TMR Processor

fault containment region.
