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
• www.analog.com/lwip
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.
