7.18 Security Accelerator
The security accelerator provides wire-speed processing on 1-Gbps Ethernet traffic on IPSec, SRTP, and 3GPP Air interface security protocols. It functions on the packet level with the packet and the associated security context being one of these above three types. The security accelerator is coupled with packet accelerator, and receives the packet descriptor containing the security context in the buffer descriptor, and the data to be encrypted/decrypted in the linked buffer descriptor.
7.19 Ethernet MAC (EMAC)
The Ethernet media access controller (EMAC) modules provide an efficient interface between the TMS320TCI6616 DSP and the networked community. The EMAC supports 10Base-T (10 Mbits/second [Mbps]), and 100BaseTX (100 Mbps), in halfor full-duplex mode, and 1000BaseT (1000 Mbps) in full-duplex mode, with hardware flow control and quality-of-service (QOS) support. For more information, see the Ethernet Media Access Control (EMAC) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 59.
Each device has a unique MAC address. There are two registers to hold these values, MACID1 (0x02620110) and MACID2 (0x02600114). All bits of these registers are defined as follows:

7.20 Management Data Input/Output (MDIO)
The management data input/output (MDIO) module implements the 802.3 serial management interface to interrogate and controls up to 32 Ethernet PHY(s) connected to the device, using a shared two-wire bus. Application software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the negotiation results, and configure required parameters in the EMAC module for correct operation. The module is designed to allow almost transparent operation of the MDIO interface, with very little maintenance from the core processor. For more information, see the Ethernet Media Access Control (EMAC) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 59.
