MVME2502 Installation and Use (6806800R96L) 77
4.2.12 Security Engine (SEC) 3.1
The integrated security engine of the P2020 is designed to off load intensive security
functions like key generation and exchange, authentication and bulk encryption from the
processor core. It includes eight different execution units where data flows in and out of an
EU.
NOTE: The standard versions of the MVME2502 do not use the encryption enabled
versions of the P2020 processor.
