The other Analog Devices IDE, VisualDSP++, supports proces-

sor families introduced prior to the release of CrossCore

Embedded Studio. This IDE includes the Analog Devices VDK

real time operating system and an open source TCP/IP stack.

For more information visit www.analog.com/visualdsp. Note

that VisualDSP++ will not support future Analog Devices

processors.

EZ-KIT Lite Evaluation Board

For processor evaluation, Analog Devices provides 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. Also available are various EZ-Extenders

®, which are

daughter cards delivering additional specialized functionality,

including audio and video processing. For more information

visit www.analog.com and search on “ezkit” or “ezextender”.

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’s PC, enabling the chosen IDE evaluation

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

the customer 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 Cross-

Core Embedded Studio or VisualDSP++ installed (sold

separately), engineers 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 its capabilities

and reduce development time. Add-ins include board support

packages for evaluation hardware, various middleware pack-

ages, 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.

Board Support Packages for Evaluation Hardware

Software support for the EZ-KIT Lite evaluation boards and EZ-

Extender daughter cards is provided by software add-ins called

Board Support Packages (BSPs). The BSPs contain the required

drivers, pertinent release notes, and select example code for the

given evaluation hardware. A download link for a specific BSP is

located on the web page for the associated EZ-KIT or EZ-

Extender product. The link is found in the Product Download

area of the product web page.

Middleware Packages

Analog Devices separately offers middleware add-ins such as

real time operating systems, file systems, USB stacks, and TCP/

IP stacks. For more information see the following web pages:

• www.analog.com/ucos3

• www.analog.com/ucfs

• www.analog.com/ucusbd

Algorithmic Modules

To speed development, Analog Devices offers add-ins that per-

form popular audio and video processing algorithms. These are

available for use with both CrossCore Embedded Studio and

VisualDSP++. For more information visit www.analog.com and

search on “Blackfin software modules” or “SHARC software

modules”.

Designing an Emulator-Compatible DSP Board (Target)

For embedded system test and debug, Analog Devices provides

a family of emulators. On each JTAG DSP, Analog Devices sup-

plies an IEEE 1149.1 JTAG Test Access Port (TAP). In-circuit

emulation is facilitated by use of this JTAG interface. The emu-

lator accesses the processor’s internal features via the

processor’s TAP, allowing the developer to load code, set break-

points, and view variables, memory, and registers. The

processor must be halted to send data and commands, but once

an operation is completed by the emulator, the DSP system is set

to run at full speed with no impact on system timing. The emu-

lators require the target board to include a header that supports

connection of the DSP’s JTAG port to the emulator.

For details on target board design issues including mechanical

layout, single processor connections, signal buffering, signal ter-

mination, and emulator pod logic, see the Engineer-to-Engineer

Note “Analog Devices JTAG Emulation Technical Reference”

(EE-68) on the Analog Devices website (www.analog.com)—use

site search on “EE-68.” This document is updated regularly to

keep pace with improvements to emulator support.
