The protocol converter
The ARM9E-S
An interface, such as an RS232 or parallel connection, connects the debug host to the
ARM9E-S development system. The messages broadcast over this connection must be
converted to the interface signals of the ARM9E-S. The protocol converter performs
this conversion.
The ARM9E-S has hardware extensions that ease debugging at the lowest level. The
debug extensions:
•
•
•
•
The major blocks of the ARM9E-S are:
ARM9E-S core
EmbeddedICE-RT logic
TAP controller
These blocks are shown in Figure 7-2 on page 7-5.

This is the CPU core, with hardware support for debug.
This is a set of registers and comparators used to generate debug
exceptions (such as breakpoints). This unit is described in About
EmbeddedICE-RT on page 7-6.
This controls the action of the scan chains using a JTAG serial
interface.
