VXI-1394 User Manual for Windows

What is shared memory and dual-ported memory?

These terms refer to a block of memory that is accessible to both a client
and a server. The memory block operates as a message buffer for
communications. Shared memory is applicable only if you are using either
A24 or A32 address space.
