The power dissipated by a processor is largely a function of the

clock frequency and the square of the operating voltage. For

example, reducing the clock frequency by 25% results in a 25%

reduction in dynamic power dissipation.

Target Board JTAG Emulator Connector

The Analog Devices DSP tools product line of JTAG emulators

uses the IEEE 1149.1 JTAG test access port of the processors to

monitor and control the target board processor during emula-

tion. The Analog Devices DSP tools product line of JTAG

emulators provides emulation at full processor speed, allowing

inspection and modification of memory, registers, and proces-

sor stacks. The processor JTAG interface ensures the emulator

does not affect target system loading or timing.

For information on JTAG emulator operation, see the appropri-

ate emulator hardware user’s guide at SHARC Processors

Software and Tools.

SYSTEM DEBUG

The processors include various features that allow easy system

debug. These are described in the following sections.

System Watchpoint Unit (SWU)

The system watchpoint unit (SWU) is a single module that

connects to a single system bus and provides transaction moni-

toring. One SWU is attached to the bus going to each system

slave. The SWU provides ports for all system bus address chan-

nel signals. Each SWU contains four match groups of registers

with associated hardware. These four SWU match groups

operate independently but share common event (for example,

interrupt and trigger) outputs.

Debug Access Port (DAP)

Debug access port (DAP) provides IEEE 1149.1 JTAG interface

support through the JTAG debug. The DAP provides an

optional instrumentation trace for both the core and system. It

provides a trace stream that conforms to MIPI System Trace

Protocol version 2 (STPv2).

DEVELOPMENT TOOLS

Analog Devices supports its processors with a complete line of

software and hardware development tools, including an inte-

grated development environment (CrossCore

® Embedded

Studio), evaluation products, emulators, and a variety of soft-

ware add ins.

Integrated Development Environments (IDEs)

For C/C++ software writing and editing, code generation, and

debug support, Analog Devices offers the CrossCore Embedded

Studio integrated development environment (IDE).

CrossCore Embedded Studio is based on the Eclipse framework.

Supporting most Analog Devices processor families, it is the

IDE of choice for processors, including multicore devices.

CrossCore Embedded Studio seamlessly integrates available

software add ins to support real time operating systems, file

systems, TCP/IP stacks, USB stacks, algorithmic software mod-

ules, and evaluation hardware board support packages. For

more information, visit www.analog.com/cces.

EZ-KIT Lite Evaluation Board

For processor evaluation, Analog Devices provides a wide range

of EZ-KIT Lite

® evaluation boards. Including the processor and

key peripherals, the evaluation board also supports on-chip

emulation capabilities and other evaluation and development

features. Various EZ-Extenders

® are also available, which are

daughter cards that deliver additional specialized functionality,

including audio and video processing. For more information

visit www.analog.com.

EZ-KIT Lite Evaluation Kits

For a cost-effective way to learn more about developing with

Analog Devices processors, Analog Devices offer a range of EZ-

KIT Lite evaluation kits. Each evaluation kit includes an EZ-KIT

Lite evaluation board, directions for downloading an evaluation

version of the available IDE(s), a USB cable, and a power supply.

The USB controller on the EZ-KIT Lite board connects to the

USB port of the user PC, enabling the chosen IDE evaluation

suite to emulate the on-board processor in circuit. This permits

users to download, execute, and debug programs for the EZ-

KIT Lite system. It also supports in circuit programming of the

on-board Flash

® device to store user specific boot code,

enabling standalone operation. With the full version of

CrossCore Embedded Studio installed (sold separately), engi-

neers can develop software for supported EZ-KITs or any

custom system utilizing supported Analog Devices processors.

Software Add Ins for CrossCore Embedded Studio

Analog Devices offers software add ins which seamlessly inte-

grate with CrossCore Embedded Studio to extend the

capabilities and reduce development time. Add ins include

board support packages for evaluation hardware, various mid-

dleware packages, and algorithmic modules. Documentation,

help, configuration dialogs, and coding examples present in

these add ins are viewable through the CrossCore Embedded

Studio IDE once the add in is installed.
