ADSP-BF534/ADSP-BF536/ADSP-BF537

VCSE is Analog Devicesâ technology for creating, using, and

reusing software components (independent modules of sub-

stantial functionality) to quickly and reliably assemble software

applications. Components can be downloaded from the Web

and dropped into the application. Component archives can be

published from within VisualDSP++. VCSE supports compo-

nent implementation in C/C++ or assembly language.

The expert linker can be used to visually manipulate the place-

ment of code and data in the embedded system. Memory

utilization can be viewed in a color-coded graphical form. Code

and data can be easily moved to different areas of the processor

or external memory with the drag of the mouse. Runtime stack

and heap usage can be examined. The expert linker is fully com-

patible with existing linker definition file (LDF), allowing the

developer to move between the graphical and textual

environments.

Analog Devices emulators use the IEEE 1149.1 JTAG test access

port of the Blackfin to monitor and control the target board

processor during emulation. The emulator provides full-speed

emulation, allowing inspection and modification of memory,

registers, and processor stacks. Nonintrusive in-circuit emula-

tion is assured by the use of the processorâs JTAG interfaceâthe

emulator does not affect target system loading or timing.

In addition to the software and hardware development tools

available from Analog Devices, third parties provide a wide

range of tools supporting the Blackfin processor family. Third

party software tools include DSP libraries, real-time operating

systems, and block diagram design tools.

EZ-KIT LiteÂ® Evaluation Board

For evaluation of ADSP-BF534/ADSP-BF536/ADSP-BF537

processors, use the ADSP-BF537 EZ-KIT Lite board available

from Analog Devices. Order part number ADDS-BF537-

EZLITE. The board comes with on-chip emulation capabilities

and is equipped to enable software development. Multiple

daughter cards are available.

DESIGNING AN EMULATOR-COMPATIBLE

PROCESSOR BOARD

The Analog Devices family of emulators are tools that every sys-

tem developer needs in order to test and debug hardware and

software systems. Analog Devices has supplied an IEEE 1149.1

JTAG Test Access Port (TAP) on each JTAG processor. The

emulator uses the TAP to access the internal features of the pro-

cessor, allowing the developer to load code, set breakpoints,

observe variables, observe memory, and examine registers. The

processor must be halted to send data and commands, but once

an operation has been completed by the emulator, the processor

system is set running at full speed with no impact on

system timing.

To use these emulators, the target board must include a header

that connects the processorâs JTAG port to the emulator.

For details on target board design issues including mechanical

layout, single processor connections, multiprocessor scan

chains, signal buffering, signal termination, and emulator pod

logic, see Analog Devices JTAG Emulation Technical Reference

(EE-68) on the Analog Devices website under

www.analog.com/ee-notes. This document is updated regularly

to keep pace with improvements to emulator support.
