5.4 Local Memory Map

5.4.2 Shared Memory

The shared memory is a 4-kByte section of the local SRAM and runs from $100000 through $100FFF, as seen by the local processor. VMEbus masters can access this shared SRAM in the VMEbus standard (A24) address space. The access address for VMEbus masters is installed at a 4-kByte boundary using the module ID.

The starting address is calculated as follows: $C00000 + (Module ID x $1000). The next figure shows the address bits used by the VMEbus address comparator.
