Processor
The PowerPC has become the most widely used of the new generation of RISC processors. Its pedigree
is unequalled - jointly developed by world-leading computer companies and backed by long-term
commitments from major OEMs.
PowerPC 7455
The PowerPC 7455 is a 32-bit superscalar RISC processor, clocked at 933 MHz and above, with the
following features:
•
64-bit external data bus
•
On-chip 32 Kbyte instruction and data caches
•
On-chip 256 Kbyte of L2 Cache
•
Enhanced branch prediction capabilities
•
MMU and integral FPU
•
On-chip L3 cache controller that connects to a private L3 cache bus operating at up to 200 MHz
The PowerPC 7455 implements a fully static architecture and offers sophisticated power management
capabilities. As a result, its maximum power consumption is less than 20 Watts at 933 MHz.

Note:
The above estimated values are supplied by Motorola Semiconductor, and illustrate the performance and
power dissipation of the CPU. Radstone PowerX SBCs are designed to take the processor, providing a
balanced general-purpose platform. The actual performance and power dissipation may vary depending
on the application being run and resource usage of the configured system.
