Details on power consumption and Static and Dynamic current
consumption can be found at Total Power Dissipation on
information.
The following are SVS features.
SVS is applicable only to 450 MHz models (not applicable
to 400 MHz or lower frequency models).
Each individual SVS device includes a register (SVS_DAT)
containing the unique SVS voltage set at the factory, known
as SVSNOM.
The SVSNOM value is the intended set voltage for the
VDD_INT voltage regulator.
No dedicated pins are required for SVS. The TWI serial bus
is used to communicate SVSNOM to the voltage regulator.
Analog Devices recommends a specific voltage regulator
design and initialization code sequence that optimizes the
power-up sequence.
The Engineer-to-Engineer Note “Static Voltage Scaling for
ADSP-2148x Processors” (EE-357) contains the details of
the regulator design and the initialization requirements.
Any differences from the Analog Devices recommended
programmable regulator design must be reviewed by Ana-
log Devices to ensure that it meets the voltage accuracy and
range requirements.
Target Board JTAG Emulator Connector
Analog Devices DSP Tools product line of JTAG emulators uses
the IEEE 1149.1 JTAG test access port of the ADSP-2148x pro-
cessors to monitor and control the target board processor
during emulation. Analog Devices DSP Tools product line of
JTAG emulators provides emulation at full processor speed,
allowing inspection and modification of memory, registers, and
processor stacks. The processor’s JTAG interface ensures that
the emulator will not affect target system loading or timing.
For complete information on Analog Devices’ SHARC DSP
Tools product line of JTAG emulator operation, see the appro-
priate emulator hardware user’s guide.
DEVELOPMENT TOOLS
Analog Devices supports its processors with a complete line of
software and hardware development tools, including integrated
development environments (which include CrossCore
Embed-
ded Studio and/or VisualDSP++
), evaluation products,
emulators, and a wide variety of software add-ins.
Integrated Development Environments (IDEs)
For C/C++ software writing and editing, code generation, and
debug support, Analog Devices offers two IDEs.
The newest IDE, CrossCore Embedded Studio, is based on the
EclipseTM framework. Supporting most Analog Devices proces-
sor families, it is the IDE of choice for future 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 modules, and evaluation hardware board
support packages. For more information visit
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.
