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:
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.
ADDITIONAL INFORMATION
This data sheet provides a general overview of the ADSP-2148x
architecture and functionality. For detailed information on the
ADSP-2148x family core architecture and instruction set, refer
to the SHARC Processor Programming Reference.
RELATED SIGNAL CHAINS
A signal chain is a series of signal-conditioning electronic com-
ponents that receive input (data acquired from sampling either
real-time phenomena or from stored data) in tandem, with the
output of one portion of the chain supplying input to the next.
Signal chains are often used in signal processing applications to
gather and process data or to apply system controls based on
analysis of real-time phenomena. For more information about
this term and related topics, see the “signal chain” entry in the
Glossary of EE Terms on the Analog Devices website.
Analog Devices eases signal processing system development by
providing signal processing components that are designed to
work together well. A tool for viewing relationships between
specific applications and related components is available on the
www.analog.com website.
provides:
Graphical circuit block diagram presentation of signal
chains for a variety of circuit types and applications
Drill down links for components in each chain to selection
guides and application information
Reference designs applying best practice design techniques
