Selecting a Target System

1-9

If you need to use a number of form factors throughout a project, we

recommend that you use PMC I/O boards because you can use them in

CompactPCI, desktop PC, rack-mount PC, or PC/104 systems. You achieve this

flexibility by plugging the PMC I/O boards into a passive carrier board for the

corresponding form factor. This justifies your investment in I/O boards when

you have to consider another form factor at a later stage. For example, you may

start with one form factor in the laboratory and then choose another form

factor for field tests.

“Selecting a Target System Using the xPC Target Interactive Hardware

Selection Guide” on page 1-10 describes how to use the xPC Target Interactive

Hardware Selection Guide to help you select an I/O board supported by xPC

Target.

boards.

Older standard with

performance similar to ISA

Most IP modules use the slow

8MHz bus, but some support

the 32MHz bus clock.

Requires carrier boards,

which can be expensive
