• Manufacturer Part Number: ADSP-BF522
• Description: Blackfin Embedded Processor
• Manufacturer: AD [Analog Devices]

Preliminary Technical Data
The assembly language, which takes advantage of the proces-
sor’s unique architecture, offers the following advantages:
DEVELOPMENT TOOLS
The processor is supported with a complete set of
CROSSCORE® software and hardware development tools,
including Analog Devices emulators and VisualDSP++® devel-
opment environment. The same emulator hardware that
supports other Blackfin processors also fully emulates the
ADSP-BF522/524/526 and ADSP-BF523/525/527 processors.
EZ-KIT Lite® Evaluation Board
For evaluation of ADSP-BF522/524/526 and
ADSP-BF523/525/527 processors, use the EZ-KIT Lite boards
available from Analog Devices. Order using part numbers
ADZS-BF526-EZLITE or ADZS-BF527-EZLITE. The boards
come with on-chip emulation capabilities and is equipped to
enable software development. Multiple daughter cards are
available.
DESIGNING AN EMULATOR-COMPATIBLE
PROCESSOR BOARD (TARGET)
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 processor’s JTAG port to the emulator.

layout, single processor connections, multiprocessor scan
chains, signal buffering, signal termination, and emulator pod
logic, see (EE-68) Analog Devices JTAG Emulation Technical
