It's very common for ARM systems to have disparate processors. My GP2X handheld is dual core system. It has a regular ARM processor and then a second processor for accelerating some types of multimedia functions.
This goes right back to the ARM's prehistory. The BBC microcomputer's 'Tube' coprocessor interface springs to mind, allowing you to plug in coprocessors with arbitrary buses, interfacing them to the host machine via a set of FIFOs. People tended to call the coprocessor 'the Tube' as well, which was a bit confusing given how variable the CPUs were that you could plug in there.
