Memory Maps

There are two points of view for memory maps: 1) the mapping of all resources as viewed by local bus masters (local bus memory map), 2) the mapping of onboard resources as viewed by externa masters (VMEbus memory map or VSB memory map).

Local Bus Memory Map

The local bus memory map is split into different address spaces by the transfer type (TT) signals. The local resources respond to the normal access and interrupt acknowledge codes.

Normal Address Range

The memory map of devices that respond to the normal address range is shown in the following tables. The normal address range is defined by the Transfer Type (TT) signals on the local bus. On the MVME166, Transfer Types 0, 1, and 2 define the normal address range.

Table 1-2 is the entire map from $00000000 to $FFFFFFFF. Many areas of the map are user-programmable, and suggested uses are shown in the table. The cache inhibit function is programmable in the MMUs. The onboard I/O space must be marked cache inhibit and serialized in its page table.

Table 1-3 further defines the map for the local I/O devices.
