RealView ICE and RealView Trace

RealView ICE

The RealView ICE run control unit is the ARM leading-edge software debug hardware that

enables the RealView Development Suite debug software to connect to and control Freescale

wireless and mobile silicon. The RealView ICE unit delivers the performance required by today’s

developers of embedded system software on Freescale wireless and mobile silicon.

The RealView ICE unit is an essential tool in an ARM system debug environment for connection

and access to devices that contain the EmbeddedICE

logic, Embedded Trace Macrocell™

(ETM™) and Embedded Trace Buffer™ (ETB™) components for on-chip trace data storage. The

unit has the ability to be expanded with additional modules for extended functionality, such as

the RealView Trace module for trace data capture.

The RealView ICE unit can also be used with the open-source Eclipse Integrated Development

Environment and the GNU debugger, gdb, to provide a single JTAG connection for both kernel

and application debug for Linux and other similar operating system environments.

Key Features

• High-performance debug control, with code download up to 1300 kbps and high-speed

single-stepping—up to 100 steps/sec

• Support for variable JTAG clock frequencies, 2 kHz to 20 MHz or 50 MHz (LVDS ); very low

JTAG clock frequencies (sub-1kHz) support ASIC-emulation environments

• Support for Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB)

• USB 1.1 and 2.0 compatible connection (Windows platform only)

• Ethernet 10/100baseT remote and local host connection

• GDB-Eclipse plug-in for simplified connection and debug with the GNU debugger

• Host platforms: Windows and Linux

RealView Trace

The RealView Trace module, an optional expansion module for the RealView ICE run control unit,

provides the off-chip trace data capture capability for the Embedded Trace Macrocell components.

The RealView Trace module enables non-invasive, real-time tracing of instruction execution and data

transactions when used in conjunction with the debugger in RealView Development Suite. Trace

capture conditions may be defined using a set of powerful trigger conditions in the debugger. Once

trace capture has occurred, the debugger provides multiple display options to quickly hone in on

code hotspots or bugs. Captured trace data may be used to provide an execution profile, enabling

developers to quickly analyze critical code sections such as boot time, interrupt latency and task

switching overhead.

Key Features

• Trace clock speeds up to 250 MHz; half-rate clocking up to 125 MHz

• Non-invasive, real-time tracing of instructions and data

• 4/8/16 bit data width trace port

• Supports ETM7™, ETM9™ and ETM11™ protocols

• ETM trace port modes supported

• Supports Windows XP platform
