Abstract
Official abstract text for this publication.
A method of processing data in a data processor comprising at least two data processing units. The method comprises performing different data processing steps in the data processing units concurrently during a parallel operation, and replicating performances of selected identical data processing steps in the data processing units during a non-synchronised redundant operation. The non-synchronised redundant operation comprises an initial performance of the selected identical data processing steps in one of the data processing units and a replicate performance of the data processing steps starting later than the initial performance, preferably in another of the data processing units. Initial result data representative of results from the initial performance are registered, and compared with replicate result data representative of results from the replicate performance, and an error signal is produced in case of discrepancy.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of processing data in a data processor comprising a first data processing unit and a second data processing unit, the method comprising: performing first data processing steps in said first data processing unit concurrently with second data processing steps in said second data processing unit during a parallel operation; and replicating performances of third data processing steps in said first and second data processing units during a non-…
