    摘要: Each of (n−1) 2-bit checking units, where n is an integer larger than or equal to 4, receives n-bit redundant encoded data generated from 1-bit input data, and outputs 2-bit check data based on a result of comparison between bits of the encoded data, combinations of the bits differing in each comparison. An all-bit checking unit outputs all-bit check data based on exclusive ORs of all-bit of the encoded data. An error detecting unit detects errors in the encoded data on the basis of the (n−1) sets of 2-bit check data and the all-bit check data, and outputs the input data on the basis of the result of error detection.

    摘要: A DMA apparatus which reads data corresponding to a descriptor from memory, and a dividing unit in a descriptor management device divides one descriptor into a plurality of sub-descriptors. A plurality of DMA controllers produce a plurality of reading requests for reading data corresponding to the plurality of sub-descriptors from the memory. A memory controller reads the corresponding data from the memory according to the plurality of reading requests.
