If higher performance is needed, just move to the MPC8548. This device is a networking/telecom processor which operates up to 1.5GHz core frequency with a 64-bit DDR/DDR2 controller scaling up to 533MHz data rate and 512KB of L2 cache. The dual 32-bit PCI or 64-bit PCI-X feature 4-bit serial RapidIO fabric technology and 4-bit PCI Express or single 8-bit PCI Express 1.0a, XOR acceleration, local bus I/O interfaces and four Gigabit Ethernet interfaces. The MPC8544, MPC8533, MPC8536, and MPC8548 are available with an integrated security engine on the ‘E’ version only.
