Intel XScale IOP321
The LinuxLink software distribution model enables the usage of the Intel IOP321 LinuxLink for development targeting all designs based on Intel 80321 XScale microarchitecture processor. The Intel IOP321® I/O processor is Intel's fifth generation I/O processor. It is the first I/O processor to integrate an Intel XScale® microarchitecture core and a PCI-X interface.
Processor derivatives enabled:
The Intel Intel IOP321 LinuxLink can also be used as a starting point for Linux development for designs based the IOP310 I/O processor chipset and the Intel StrongARM* microprocessor (SA-110), simplifying code porting from existing designs.
Reference boards/OEM boards enabled:
The Intel Intel IOP321 LinuxLink can also be used as a starting point for Linux development for designs derived from:
Notes:
Complete peripheral support for Intel IOP321 derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
