Intel IXA SDK ACE Programming Framework - Department of ...

The Application Building Process
6. Define the crosscalls with which ACEs and the manager program will communicate:
a. Define crosscall interfaces in IXA IDL.
b. Compile the interface definitions with the IXA IDL compiler tao_idl. This
produces a set of C headers and source files that define crosscalls and crosscall
references.
c. Edit the generated crosscall source to define the call methods.
d. If needed, edit the generated callback sources to define callbacks for asynchronous
calls.
For more information, see Chapter 11, “Communication Within an Application.”
7. Implement initialization code for each ACE in C.
a. Define an initialization function to create the ACE and its related objects
(targets, sets, and so on). See “Creating ACEs” on page 22.
b. Define methods and utility functions.
c. Include the crosscall headers as needed (depending on whether the ACE is
acting as a call server or call client). Initialize each crosscall interface in both
the server and the client. See Chapter 11, “Communication Within an Application.”
8. Create the ACE executable for each ACE.
a. Compile the NCL code using nclcomp, then gcc.
b. Compile the action, initialization, and crosscall code using gcc.
c. Link the rules object, action object, initialization object, and crosscall objects
using ld.
You typically use a makefile to do this. For more information, see Chapter 3,
“Compiling and Testing Applications.”
9. Modify the startup script’s configuration file, ixsys.config:
a. Specify and configure the ports you are using.
b. Create and start the microACEs, specifying a microcode image for each type
of port.
c. Create and start the conventional ACEs, passing in a pointer to the single
object executable.
d. Bind targets and ACEs to determine packet flow in the application.
e. Run the configuration scripts for any library ACEs you are using.
For more information, see Chapter 4, “Configuring and Starting IXA Systems.”
10. Create a runtime, downloading the application and operating system to IXP1200
flash. For the development system:
a. Open a remote shell to the IXDP1200 Advanced Development Platform from
the Linux development workstation.
b. Mount the workstation’s NFS directory on the IXP200.
