Debug systems
Debug host
Protocol converter
A debug system typically has three parts:
•
•
•
The debug host and the protocol converter are system-dependent.
The debug host is a computer that is running a software debugger such as the ARM
Debugger for Windows (ADW). The debug host allows you to issue high-level
commands such as setting breakpoints or examining the contents of memory.
The protocol converter communicates with the high-level commands issued by the
debug host and the low-level commands of the ARM7TDMI processor JTAG interface.
Typically it interfaces to the host through an interface such as an enhanced parallel port.
Figure 5-1 shows a typical debug system using an ARM core.
