<h2>The Dual Core: One Application Per Core Approach to Programming the ADSP-BF609</h2>
<p>
You have created a project that uses the dual core, one application per core programming
model for the ADSP-BF609 processor. In this approach, each core is treated as a
separate processor, and each project is built individually. Effectively, two
single-core applications are built independently, and run in parallel on the
processor. The shared memory areas, both internal and external, are left to the
developer to arrange for shared, serializable access from each of the cores.
</p>
<p>
If you selected the 'Add template code to the application' option in the
Project Wizard, your project will contain template code to help you get
started, including a 'main' function for both cores. If you did not
select the option, you will need to declare your own 'main' functions. A 'main'
function must be declared for both cores.
</p>
<p>
To get started with your application, begin adding your source code to the
'main' function in both projects. If you are defining your own, you must
include a call to the 'adi_core_1_enable()' function in your Core-0 project.
This function allows Core-0 to enable Core-1, and is declared in ccblkfn.h.
If you selected the 'Add template code to the application' option this function call
is automatically added to your 'main' functions in each project.
