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.
Use the expert linker to visually manipulate the placement of
code and data on the embedded system. View memory utiliza-
tion in a color coded graphical form, easily move code and data
to different areas of the processor or external memory with the
drag of the mouse, and examine runtime stack and heap usage.
The expert linker is fully compatible with existing linker defini-
tion 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 ADSP-BF531/ADSP-BF532 processor 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. Non-
intrusive in-circuit emulation is assured by the use of the
processor’s JTAG interface—the 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. Hard-
ware tools include Blackfin processor PC plug-in cards. Third
party software tools include DSP libraries, real-time operating
systems, and block diagram design tools.

DESIGNING AN EMULATOR-COMPATIBLE
PROCESSOR BOARD
The Analog Devices family of emulators are tools that every sys-
tem developer needs 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 processor, allow-
ing the developer to load code, set breakpoints, observe
variables, observe memory, and examine registers. The proces-
sor 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 processor’s 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 the
