Claim 0:
1. A method of cluster interlayer neural network tensor data flow path failure detection for use in a neural network processor, the method comprising:
providing a stream of tensors to be written to a memory;
calculating a first cyclic redundancy code (CRC) checksum on each said data tensor over all real features;
writing said tensors together with said first CRC checksums to said memory;
wherein each first CRC checksum is generated across a plurality of real features of a corresponding tensor and stored in said memory as an additional CRC feature of the tensor;
subsequently reading said stream of tensors and corresponding CRC feature of first CRC checksums from said memory and generating a second CRC checksum on said read tensors; and
verifying whether said second CRC checksums match said first CRC checksums and generating an error if a mismatch is detected.
