hi
i am new in dsp world.
i am using adsp 2181 for my application.
on chip memory is not sufficient for my application code.
so i have used software overlay for application code.
but i want to know that can i used hardware overlay for same application?
suppose i can use then how can i placed some application code in external RAM? how can i change my LDF to link some code in external memory?
one more thing which i want to know that how can i use both software and hardware overlay for application.
