I/O Components

The Nintendo 64 I/O software subsystem consists of the following major components:

- system exception handler
- device manager for shared devices
- device-dependent system interface.

The figure below shows the interaction between some of these components to service an I/O request. This interaction assumes that the device is not shared, and therefore, requires no mutual exclusion.
