JTAG Debugger
What is Debugger?
The purpose of a debugging tool called debugger (for instance GDB) is to allow the developers to monitor the behaviour of a programme while it executes, or the behaviour of the programme at the moment it crashed (Stallman, 2003)
What is JTAG?
The Boundary Scan/JTAG, formally known as IEEE/ANSI standard 1149.1_1190, is a set of

by several North American and European companies.
