Abstract: A method and system for overriding selected ROM code functions or adding new ROM code functions within a processing system. A system designer determines an existing ROM address for the selected existing code function or a desired ROM address for the new code function. The system designer then programs a patch to replace the selected existing code function or programs a new code function. The patch or new code function is then loaded into a first memory. A loader module is also programmed and loaded into the first memory. Upon system boot-up, the loader module transfers any patches or new code functions within the first memory into a second memory that is memory-mapped to the ROM. This second memory can be accessed by the processor at a faster rate than the processor can access ROM. During a processor request cycle, the processor first examines the second memory for the presence of a desired ROM code function.

Abstract: A method, apparatus, and article of manufacture for a computer implemented packet processor. The packet processor processes packets in parallel. In particular, the packet processor performs a combination of encryption and authentication on data packets. The encryption and authentication processing of a second data packet may begin before the encryption and authorization processes of a first data packet have completed.
