They are NOT coprocessors, as you seem to be implying, as that's the word used to describe a "dependant processor" which isn't actually capable of independant operation. The SPUs are -- thus, they are independant cores.
Correct, the SPEs are independent systems within which the SPU acts as a CPU which can do just about anything with proper care. They can facilitate almost any kind of functionality, nearly all game code preferably runs on here for optimal results.
