ARM NEON question

I've been reading about this and one thing is puzzling me: does each CPU core have its own NEON unit, or is it shared between all CPU cores? The docs I've looked at refer to it as the "NEON unit", and it's physically in a separate location to the CPU cores on chip. If it is just a single unit, then what's the normal procedure for allowing multi-threaded/multi-core programs to share access to it? Unfortunately, I wasn't able to find an answer to either of these questions on the web, so I thought that maybe someone here would know. Thanks.
