Debug systems
The debug host
The protocol converter
The ARM9TDMI forms one component of a debug system that interfaces from the
high-level debugging performed by the user to the low-level interface supported by the
ARM9TDMI. A typical system is shown in Figure 5-1:
Such a system typically has three parts:

These are described in the following paragraphs.
The debug host.
The protocol converter.
The ARM9TDMI on page 5-4.
The debug host is a computer, for example a personal computer, running a
software debugger such as armsd, for example, or ADW. The debug host allows
the user to issue high-level commands such as “set breakpoint at location XX”,
or “examine the contents of memory from 0x0 to 0x100”.
The debug host is connected to the ARM9TDMI development system via an
interface (an RS232, for example). The messages broadcast over this connection
must be converted to the interface signals of the ARM9TDMI. This function is
performed by the protocol converter, for example, Multi-ICE.
