4.3.3.1.3. hdcp2x_rx_kmem.v file

For hdcp2x_rx_kmem.v file
  • To identify the correct HDCP2 RX DCP key file for hdcp2x_rx_kmem.v, make sure the first 4 bytes of the file are “0x00, 0x00, 0x00, 0x02”.
  • The keys in the DCP key files are in little-endian format.
Figure 37. Byte mapping from HDCP2 RX DCP key file into hdcp2x_rx_kmem.v

Figure below shows the exact byte mapping from HDCP2 RX DCP key file into hdcp2x_rx_kmem.v.

Note: The byte number displays in below format:
  • Key size in bytes * key number + byte number in current row + constant offset + row size in bytes * row number.
  • 862*n indicates that each key set has 862 bytes.
  • 16*y indicates that each row has 16 bytes. There is an exception in cert_rx_prod where ROW 32 has only 10 bytes.

Figure 39. Wire Arrays of hdcp2x_rx_kmem.v

This figure shows the wire arrays for hdcp2x_rx_kmem.v (cert_rx_prod, kprivrx_qinv_prod, and lc128_prod) map to the example of HDCP2 RX DCP key file in Figure 38.
