Minimal PowerPC 603e Evaluation Board

 

MOTOROLA

 

Part 7  Summary

 

The EXCIMER kit is a vehicle for exploring the PowerPC architecture and simple embedded software
development. The kit is meant to be a low-cost example of a PowerPC design suitable for learning, teaching,
or experimenting. Substantive applications that require large memory, PCI devices, or other advanced
features should explore the Yellowknife platform also available from Motorola or evaluation systems from
numerous third party vendors.
