Number of Coprocessors option

Maximum number of coprocessors that can be defined in TIE to support efficient (lazy) register save/restore

Number of Coprocessors option
2

Can be set from 0 to 8. Designating a coprocessor in TIE creates a bit in a special coprocessor enable register. When that bit is set, any access to the coprocessor's registers causes an exception. The associated exception-handling routine can then save the state of the coprocessor's registers before they are used, for example, in a new context.
