5 Sample Application
This chapter presents a sample application, to be run on one Alpha and an
attached C40, which performs case reversal on its text input. Although trivial,
it illustrates the main features of a mixed network application using the
SMT401 in attached processor mode. This section does not, explain how to
perform PCI transfers via the global bus; refer to the document "SMT401
Programming Information" described in chapter 5 of this manual.
The application is split into two tasks. The first, running on the Alpha, is the
front-end. The other runs on the attached C40 processor, and performs the
actual case reversal. The application can be represented thus:
0
0
0
driver
task
caserev
task
0
Alpha
C40

5.1 Configuration File
The configuration file describes the (minimum) physical network required by
the application and the logical connections between tasks, along with
information such as the memory requirements of each task.
