4 Embedded Option
4-4
invokes the autoexec.bat file which in turn starts the xPC Target kernel on
the target PC.
If you do not provide an target application and an
autoexec.bat file to invoke
your target application, xPC Target Embedded Option starts the kernel on
your target PC and is ready to receive your target application whenever you
build and download a new one from the host computer.
In comparison, when using xPC Target without the xPC Target Embedded
Option, you can only download real-time applications to the target PC after
booting from an xPC Target boot disk. Because of this, when using xPC Target
without Embedded Option is not available, you are always required to use a
target PC equipped with a floppy disk drive. However, there are several cases
where your target system may not have a floppy disk drive or where the drive
is removed after setting up the target system. These cases can be overcome by
using the DOSLoader mode.
DOSLoader Mode Overview
With the DOSLoader mode of operation, you first set up a boot device such as
a floppy disk drive, flash disk, or a hard disk drive. This boot device must
include DOS and modules from xPC Target Embedded Option. Once the kernel
starts running, it awaits commands from the host computer and a target
application that is downloaded from the host computer. The primary purpose
of the
DOSLoader mode is to allow you to boot from devices other than the
floppy drive.
StandAlone Mode Overview
With the StandAlone mode of operation, you create completely stand-alone
applications which start execution automatically when the target PC is booted.
There is no need for communication with a host computer to downloaded the
application after booting. Once the boot device has been set up with DOS,
modules from xPC Target Embedded Option, and your target application, you
boot the target PC. Upon booting, DOS invokes your
autoexec.bat file which
invokes the kernel. However, in StandAlone mode, your target application is
combined with kernel in one binary
*.rtb file. The final result is that your
target application starts automatically each time the target PC is booted. By
using xPC Target Embedded Option, you can deploy control systems, DSP
applications, and other systems on PC hardware for use in production
