Abstract

A method for managing data transfer for a plurality of processors. Transfer messages exchanged between processor units and an external node in an integrity manager located in hardware in communication with the processor units and the external node are received. An exchange of the transfer messages is managed by the processor units with the external node based on a selected mode in mixed integrity modes such that redundantly calculated outputs from the processor units in a high integrity mode match.

Claims36

Dependent claims

A message management system comprising:

an integrity manager is configured to manage an exchange of transfer messages between processor units and an external node based on a selected mode in mixed integrity modes, wherein the integrity manager is located in hardware in communication with the processor units and the external node and checks that redundantly calculated outputs from the processor units match in a high integrity mode.

Dependencies are inferred from the claim text.
