This target is an i960Jx cpu in an 80960RP package. There is no monitor, but the flash memory is socketed and can be written with a programmer. uCR includes an ISE bootstrap loader that runs from the flash memory and loads programs into the DRAM for execution. The loader uses the PCI bus to download images.
This target is well defined, so uCR includes all the runtime files needed, including a variety of linker models, and the locore.o file to initialize the hardware. For details about the hardware, see the <em>Image Subsystem Engine - Theory of Operation</em>.
