Blackfin Low Power Imaging Platform (BLIP)

The Blackfin low power imaging platform (BLIP) integrates the

ADSP-BF707 Blackfin processor and Analog Devices software

code libraries. The code libraries are optimized to detect the

presence and behavior of humans or vehicles in indoor and out-

door environments. The BLIP hardware platform is delivered

preloaded with the occupancy software module.

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 CrossCore Embedded Studio. 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 DAP-enabled processor, Analog

Devices supplies an IEEE 1149.1 JTAG test access port (TAP),

serial wire debug port (SWJ-DP), and trace capabilities. 

In-circuit emulation is facilitated by use of the JTAG or SWD

interface. The emulator accesses the processor’s internal fea-

tures through the processor’s TAP, allowing the developer to

load code, set breakpoints, and view variables, memory, and

registers. The emulators require the target board to include a

header(s) that supports connection of the processor’s DAP to

the emulator for trace and debug.

Analog Devices emulators actively drive JTG_TRST high.

Third-party emulators may expect a pull-up on JTG_TRST and

therefore will not drive JTG_TRST high. When using this type

of third-party emulator JTG_TRST must still be driven low

during power-up reset, but should subsequently be driven high

externally before any emulation or boundary-scan operations.

See Power-Up Reset Timing on Page 61 for more information

on POR specifications.

For more details on target board design issues including

mechanical layout, single processor connections, signal buffer-

ing, signal termination, and emulator pod logic, contact the

factory for more information.

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.

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 application signal chains page in the Circuits from the Lab

site (http:\\www.analog.com\circuits) 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
