Application

Module Configuration

The 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.
