Abstract
A semiconductor integrated circuit for scrambling data and transferring the data to a transfer destination circuit includes: a scrambler that generates a scramble key and scrambles the data using the scramble key to generate scrambled data, the scramble key having a Hamming weight of B/2 when B is an even number and having a Hamming weight of (B+1)/2 or (B−1)/2 when B is an odd number where B denotes a bus width of the data; and a transfer controller that transfers the scrambled data to the transfer destination circuit.
Claims10
A semiconductor integrated circuit for scrambling data and transferring the data to a transfer destination circuit, the semiconductor integrated circuit comprising:
- a scrambler that generates a scramble key and scrambles the data using the scramble key to generate scrambled data, the scramble key having a Hamming weight of B/2 when B is an even number and having a Hamming weight of (B+1)/2 or (B−1)/2 when B is an odd number where B denotes a bus width of the data;
- and
- a transfer controller that transfers the scrambled data to the transfer destination circuit.
A data transfer method performed by a semiconductor integrated circuit for scrambling data and transferring the data to a transfer destination circuit, the data transfer method comprising:
- generating a scramble key and scrambling the data using the scramble key to generate scrambled data, the scramble key having a Hamming weight of B/2 when B is an even number and having a Hamming weight of (B+1)/2 or (B−1)/2 when B is an odd number where B denotes a bus width of the data;
- and
- transferring the scrambled data to the transfer destination circuit.
