1.2.4
The SEC is a modular and scalable security core optimized to process all the algorithms associated with
IPSec, IKE, WTLS/WAP, SSL/TLS, and 3GPP. Although it is not a protocol processor, the SEC is
designed to perform multi-algorithmic operations (for example, 3DES-HMAC-SHA-1) in a single pass of
the data. The version of the SEC used in the MPC8568E is specifically capable of performing single-pass
security cryptographic processing for SSL 3.0, SSL 3.1/TLS 1.0, IPSec, SRTP, and 802.11i.
1.2.5
The MPC8568E has two on-chip enhanced three-speed Ethernet controllers (eTSECs). The eTSECs
incorporate a media access control (MAC) sublayer that supports 10- and 100-Mbps and 1-Gbps
Ethernet/802.3 networks with MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces. The eTSECs
include 2-Kbyte receive and 10-Kbyte transmit FIFOs and DMA functions.
The MPC8568E eTSECs support programmable CRC generation and checking, RMON statistics, and
jumbo frames of up to 9.6 Kbytes. Frame headers and buffer descriptors can be forced into the L2 cache
to speed classification or other frame processing. They are IEEE Std 802.3™, IEEE 802.3u, IEEE 802.3x,
IEEE 802.3z, IEEE 802.3ac, IEEE 802.3ab-compatible.
The buffer descriptors are based on the MPC8260 and MPC860T 10/100 Ethernet programming models.
Each eTSEC can emulate a PowerQUICC III TSEC, allowing existing driver software to be re-used with
minimal change.
