Abstract: A device includes a data path, a first interface connected to the data path and configured to receive a request from a processor package to write a data value to a memory address, and a controller connected to the data path and configured to receive the request to write the data value to the memory address and to calculate a Hamming code of the data value. The controller is configured to transmit the data value and the Hamming code on the data path. The device includes an external memory interleave connected to the data path. The external memory interleave is configured to receive the data value and calculate a test Hamming code of the data value and to determine whether to send the data value to an external memory interface to be written to the memory address based on a comparison of the Hamming code and the test Hamming code.

Abstract: Disclosed embodiments include a data processing apparatus having a processing core, a memory, and a streaming engine. The streaming engine is configured to receive a plurality of data elements stored in the memory and to provide the plurality of data elements as a data stream to the processing core, and includes an address generator to generate addresses corresponding to locations in the memory, a buffer to store the data elements received from the locations in the memory corresponding to the generated addresses, and an output to supply the data elements received from the memory to the processing core as the data stream.
