MMUless pseudo mips embedded CPU. Hardwired TLB's for KSEG etc. Also a few
other cute suprises such as multiply being interruptible and the irq handler
having to save cpu magic registers before doing another one.
Some of the 3com routers I hacked on used variants of these beasties. I suspect
its a ucLinux target unless you have one with loadable TLB's
