Program Booting
The internal memory of the ADSP-21061 can be booted at sys-
tem power-up from either an 8-bit EPROM, or a host processor.
Selection of the boot source is controlled by the BMS (boot
memory select), EBOOT (EPROM boot), and LBOOT (host
boot) pins. 32-bit and 16-bit host processors can be used for
booting.
PORTING CODE FROM THE ADSP-21060 OR
ADSP-21062
The ADSP-21061 is pin compatible with the ADSP-21060/
ADSP-21061/ADSP-21062 processors. The ADSP-21061 pins
that correspond to the link port pins of the ADSP-21060/
ADSP-21062 are no-connects.
The ADSP-21061 is object code compatible with the
ADSP-21060/ADSP-21062 processors except for the following
functional elements:
The ADSP-21061 memory is organized into two blocks
with eight columns that are 4k deep per block. The
ADSP-21060/ADSP-21062 memory has 16 columns per
block.
Link port functions are not available.
Handshake external port DMA pins DMAR2 and DMAG2
are assigned to external port DMA Channel 6 instead of
Channel 8.
2-D DMA capability of the SPORT is not available.
The modify registers in SPORT DMA are not
programmable.
On the ADSP-21061, Block 0 starts at the beginning of internal
memory, normal word address 0x0002 0000. Block 1 starts at
the end of Block 0, with contiguous addresses. The remaining
addresses in internal memory are divided into blocks that alias
into Block 1. This allows any code or data stored in Block 1 on
the ADSP-21062 to retain the same addresses on the
ADSP- 21061—these addresses will alias into the actual Block 1
of each processor.
If you develop your application using the ADSP-21062, but will
migrate to the ADSP-21061, use only the first eight columns of
each memory bank. Limit your application to 8k of instructions
or up to 16k of data in each bank of the ADSP-21062, or any
combination of instructions or data that does not exceed the
memory bank.
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
Eclipse
TM 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.
