INSTRUCTION SET DESCRIPTION
The Blackfin processor family assembly language instruction set
employs an algebraic syntax designed for ease of coding and
readability. The instructions have been specifically tuned to pro-
vide a flexible, densely encoded instruction set that compiles to
a very small final memory size. The instruction set also provides
fully featured multifunction instructions that allow the pro-
grammer to use many of the processor core resources in a single
instruction. Coupled with many features more often seen on
microcontrollers, this instruction set is very efficient when com-
piling C and C++ source code. In addition, the architecture
supports both user (algorithm/application code) and supervisor
(O/S kernel, device drivers, debuggers, ISRs) modes of opera-
tion, allowing multiple levels of access to core
processor resources.
The assembly language, which takes advantage of the proces-
sor’s unique architecture, offers the following advantages:
DEVELOPMENT TOOLS
The ADSP-BF51x processors are supported with a complete set
of CROSSCORE
including Analog Devices emulators and VisualDSP++® devel-
opment environment. The same emulator hardware that
supports other Blackfin processors also fully emulates the
ADSP-BF51x processors. For more information about develop-
ment tools, visit www.analog.com.
EZ-KIT Lite Evaluation Board
For evaluation of the processors, use the EZ-KIT Lite
being developed by Analog Devices. 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 (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
• Seamlessly integrated DSP/MCU features are optimized for
• A multi-issue load/store modified-harvard architecture,
• All registers, I/O, and memory are mapped into a unified
• Microcontroller features, such as arbitrary bit and bit-field
• Code density enhancements, which include intermixing of
both 8-bit and 16-bit operations.
which supports two 16-bit MACs or four 8-bit ALUs plus
two load/store plus two pointer updates per cycle.

ming model.
manipulation, insertion, and extraction; integer operations
on 8-, 16-, and 32-bit data-types; and separate user and
supervisor stack pointers.
16-bit and 32-bit instructions (no mode switching, no code
segregation). Frequently used instructions are encoded
in 16 bits.

board
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.
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 (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
Wikipedia
website.
