The Rijndael block cipher algorithm was chosen by NIST as the new advanced encryption standard (AES). As DES is not regarded as a Standard anymore the industry would now rush into implementing AES for cryptographic implementations on their products. Being the strongest encryption algorithm which never has been broken till now, it comes with overheads like performance. Various hardware implementations for AES exist, but have their own pros & cons and there is lot of work being done in the area to achieve perfection.
The software module consists of implementing the Advanced Encryption Standard on Intelís IXP 2850. The IXP 2850 consists of two cryptographic units having hardware cores of AES, 3DES and SHA-1. It also consists of a SDK for implementing various functionalities for Network Processing.

Final Chip Design:
The tools used for chip designing are Cadence Physically Knowledgeable Synthesis (PKS) tool for Synthesis, and System On Chip (SOC) Encounter tool for Place and Route. The synthesis output is shown in figure below.
The schematic view of the synthesized AES block is also available from the PKS tool.
