Intel XScale IOP342
The new two-core Intel® IOP342 I/O processor opens the door to flexible embedded product designs enabled by a powerful blend of hardware features.
Processor derivatives enabled:
The Intel IOP342 LinuxLink can also be used as a starting point for Linux development for designs based on other IOP342 compatible processors.
Reference boards/OEM boards enabled:
The Intel IOP342 LinuxLink can also be used as a starting point for Linux development for designs derived from the IQ81342 reference board from Intel (also known as the Maple Creek).
Notes:
Complete peripheral support for Intel IOP342 derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
The Intel® Chevelon IOP342 processor combines the Intel XScale® core with powerful new features to create an intelligent I/O processor. This single function PCI device is fully compliant with the PCI Local Bus Specification, Revision 2.2.
