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 EE-68: Analog Devices

JTAG Emulation Technical Reference 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.

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.

The Circuits from the LabTM site (www.analog.com/signal

chains) 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
