Abstract: Systems and methods for servicing read requests may include receiving a transaction from a processing unit while mirroring contents from an external memory to an on-chip RAM. Such systems and methods may monitor a progress of the mirroring and, based on the monitoring, access code or data values for the transaction from either the external memory or the on-chip RAM. Such systems and methods may further provide the code or data values to the processing unit according to the transaction. Such systems and methods may allow for execution of software before software has been fully downloaded to internal memory.
