trap vector table

Trap Vector Table (TVT) is a data structure used in computer operating systems to manage system traps and exceptions. It is a table that contains pointers to the trap handlers for each type of trap or exception that the operating system handles.

When a trap or exception occurs, the processor looks up the corresponding entry in the TVT and jumps to the associated trap handler. The trap handler then takes appropriate action, such as handling the exception, resuming execution, or terminating the process.

The TVT is typically located in a fixed memory location and is initialized during system boot-up. It is used by the operating system to manage system-level exceptions, such as page faults, divide-by-zero errors, and system calls.
