1.6 Multi-Processor Architecture
The Freeway features a multi-processor architecture that separates serial protocol pro-
cessing from server management and LAN processing. Serial protocol processing is
handled by Protogate’s ICP2432B Intelligent Communications Processors (ICPs). The
ICPs are off-the-shelf PCI or PCIe bus serial I/O boards, each containing a Coldfire
5407 processor. The Freeway server processor (CPU board) is a single-board computer
based on an Intel processor.
