Migrate hardware from ADSP 21369 to 21469

Is there a migration document that addresses updating hardware from 21369 to 21469?


Is the 21469 intended to be a "simple" upgrade i.e. IO is same or superset, supply voltages same or close, supports same external memory etc.


I understand that the instruction set is similar (identical? superset?), and that one significant difference is that the 469 can execute from external memory. Are there performance metrics for internal/external execution?
