Claim 14:
15. An apparatus for cluster interlayer neural network tensor data flow path failure detection for use in a neural network processor, comprising:
a first circuit element operative to provide a stream of tensors from a previous layer to be input to a subsequent layer;
said first circuit element including a first CRC engine operative to calculate a cyclic redundancy code (CRC) checksum over said tensors wherein each CRC checksum is generated across a plurality of real features of a corresponding tensor;
a memory coupled to said first circuit element and operative to store said tensors together with corresponding CRC checksums to said memory wherein said corresponding CRC checksums are stored as an additional CRC feature of each tensor;
a second circuit element coupled to said memory and operative to read said tensors and corresponding CRC features including CRC checksums from said memory; and
said second circuit element including a second CRC engine operative to verify said CRC checksums and raise an error flag if a CRC checksum error is detected.
