Sorry if following are very naive.
What should be the attributes of a monitor implementation.
- Should it be un-modifiable.
- Does it run in normal (non-secure) mode ?
- Who programs the monitor (and its vector addresses) ?
- Would monitor intend to provide fixed services and how does it
decides that the request for a particular service is valid enough to
enter secure world ?
- Are monitors debuggable ?

thanks in advance for any kind help.
