DATA PROCESSING VALIDATION

摘要

A data processing stage is described which has a communications interface arranged to receive a plurality of input data chunks. Each input data chunk has a pointer to a validation record, where the validation records are stored at a memory accessible to the data processing stage. A processor of the data processing stage is configured to create an output validation record at the memory, and to link the output validation record to the validation records of the input chunks. The processor is configured to compute an output chunk from the input chunks in a manner which ignores data of the input chunks identified as invalid through inspection of the output validation record.

1. A data processing stage comprising:
a communications interface arranged to receive a plurality of input data chunks, each having a pointer to a validation record, the validation records stored at a memory accessible to the data processing stage; and a processor configured to create an initially empty output validation record at the memory, and to link the output validation record to the validation records of the input chunks; the processor configured to compute an output chunk from the input chunks and to either drop the output chunk or emit the output chunk dependent on inspection of the output validation record and validation records linked to the output validation record.
