Host Processor Built on

Power Architecture^™Technology

MPC7457 BLOCK DIAGRAM

The MPC7457 host processor built on Power

Architecture™ technology is a high-performance,

low-power 32-bit implementation of the RISC

architecture with a full 128-bit implementation

of Freescale’s AltiVec™ technology. AltiVec

technology allows designers to leverage existing

and customers’ requirements change—helping

speed time to market and increase system

performance without upgrading hardware. The

MPC7457 is ideal for embedded applications in

the wired and wireless telecommunications,

networking and imaging arenas, computing,

embedded network control and signal
