6.2.2 Address Invariant Data Ordering Rules
6.3 Data Transfers Across the DCS Network
The address invariance rule of the DTL interface is given in
implies the address, regardless of endian mode of the system.
Table 6: 32 Bit DTL Interface Byte Address
Modules dealing with 8, 16 or 32-bit units must place bytes on the DTL interface given
in
The DCS Network is said to be “endian neutral”. Although this bus is intended to
transfer mainly 32-bits of control and status data, it can carry smaller units of data
(8-bit, 16-bit for e.g., CPU accesses to PCI devices). Accesses on this bus are mainly
MMIO accesses. The only memory accesses allowed are for booting purposes via
the DCS Gate module. This is only accessed by the boot module. The DCS Network
is not designed for DMA burst transfers.
Modules that transfer smaller data items (8- or 16-bit) must observe the packing rules
in
