3.11.6. Width Adaptation and Data Packing in Platform Designer

Data packing applies only to systems where the data width of masters is less than the data width of slaves.

The following rules apply:

  • Data packing is supported when masters and slaves are Avalon® -MM.
  • Data packing is not supported when any master or slave is an AMBA* 3 AXI, AMBA* 4 AXI, or APB component.

For example, for a read/write command with a 32-bit master connected to a 64-bit slave, and a transaction of 2 burstcounts, Platform Designer sends 2 separate read/write commands to access the 64-bit data width of the slave. Data packing is only supported if the system does not contain AMBA* 3 AXI, AMBA* 4 AXI, or APB masters or slaves.
