Data Swapping

By default, the processor supports on-board data swapping in two manners (for all segments and DRAM technologies):

  • DQ swapping is allowed within each Byte for all DDR technologies.

  • LPDDR4x byte cannot be swizzled within their x16 sub-channel

  • LPDDR4x x16 sub-channels can be swizzled within their x32 channel
  • LPDDR4x x32 channels can be swizzled within their x64 MC

  • LPDDR5/x x16 sub-channels can be swizzle within their x64 MC

  • DDR4: Byte swapping is allowed within each x64 Channel.

  • DDR5: Byte swapping is allowed within a channel in 16-bit group: [0,1] [2,3 ].

  • ECC bits swap is allowed within ECC byte/nibble: DDR4 ECC[7..0] and DDR5 ECC[3..0].
