Abstract
Described embodiments provide a method of coordinating debugging operations in a network processor. The network processor has one or more processing modules. A system cache of the network processor requests a data transfer between the system cache and at least one external memory. A memory interface of the network processor selects an encrypted data pipeline or a non-encrypted data pipeline based on whether the processed data transfer request includes an encrypted operation. If the data transfer request includes an encrypted operation, the memory interface provides the data transfer to the encrypted data pipeline and checks whether a debug indicator is set for the data transfer request. If the debug indicator is set, the memory interface disables encryption/decryption of the encrypted data pipeline. The data transfer request is performed by the encrypted data pipeline to the at least one external memory.
