Overview
The major features of this device are as follows:
• e300c3 Power Architecture™ processor core
— High-performance, superscalar processor core with a four-stage pipeline and low interrupt
latency times
— Floating-point, dual integer units, load/store, system register, and branch processing units
— 16-Kbyte instruction cache and 16-Kbyte data cache with lockable capabilities
— Capable of completing two MACs every 3 cycles
— Dynamic power management
— Enhanced hardware program debug features
— Software-compatible with Freescale processor families implementing Power Architecture
technology
— Separate PLL that is clocked by the system bus clock
— Performance monitor
• Security engine optimized to handle all the algorithms associated with IPSec, SSL/TLS, SRTP,
IEEE 802.11i® standard, iSCSI, and IKE processing. The security engine contains one
crypto-channel, a controller, and a set of crypto execution units (EUs). The execution units are:
— Data encryption standard execution unit (DEU)
– DES and 3DES algorithms
– Two key (K1, K2) or three key (K1, K2, K3) for 3DES
– ECB and CBC modes for both DES and 3DES
— Advanced encryption standard unit (AESU)
– Implements the Rijndael symmetric-key cipher
– Key lengths of 128-, 192-, and 256-bits
– ECB, CBC, CCM, and counter (CTR) modes
— Message digest execution unit (MDEU)
– SHA with 160-, 224-, or 256-bit message digest
– MD5 with 128-bit message digest
– HMAC with either algorithm
— One crypto-channel supporting multi-command descriptor chains
– Dynamic assignment of crypto-execution units through an integrated controller
– Buffer size of 256 bytes for each execution unit, with flow control for large data sizes
– Support for multiple outstanding bus transactions
– Scatter/gather capability
– Fetch FIFOs in the crypto-channel
• DDR SDRAM memory controller
— Programmable timing supporting both DDR1 and DDR2 SDRAM
— 16-/32-bit data interface, up to 333-MHz data rate
— 512-Mbyte addressable space
