High-Speed Connectivity

Freescale’s MPC8548E processor offers

a wide range of high-speed connectivity

options, including enhanced Triple Speed

Ethernet, serial RapidIO interconnect

technology and PCI Express. Support

for these high-speed interfaces enables

scalable connectivity to network processors

and/or ASICs in the data plane while

the PowerQUICC III handles complex,

computationally demanding control plane

processing tasks. These processors also

feature next-generation double data rate

(DDR2) memory controllers, enhanced Gigabit

Ethernet support, double precision floating

point and integrated security engines that

support the Kasumi algorithm needed for

3G wireless security. In addition, support is

provided for exclusive OR (XOR) acceleration

needed for parity in storage applications.
