INSTRUCTION SET DESCRIPTION
The ADSP-218xL series assembly language instruction set has
an algebraic syntax that was designed for ease of coding and
readability. The assembly language, which takes full advantage
of the processor’s unique architecture, offers the follow-
ing benefits:
DEVELOPMENT SYSTEM
Analog Devices’ wide range of software and hardware
development tools supports the ADSP-218xL series. The DSP
tools include an integrated development environment, an evalu-
ation kit, and a serial port emulator.
VisualDSP++
allowing for fast and easy development, debugging, and deploy-
ment. The VisualDSP++ project management environment lets
programmers develop and debug an application. This environ-
ment includes an easy-to-use assembler that is based on an
algebraic syntax; an archiver (librarian/library builder); a linker;
a PROM-splitter utility; a cycle-accurate, instruction-level simu-
lator; a C compiler; and a C run-time library that includes DSP
and mathematical functions.
Debugging both C and assembly programs with the
VisualDSP++ debugger, programmers can:

The VisualDSP++ IDE lets programmers define and manage
DSP software development. The dialog boxes and property
pages let programmers configure and manage all of the
ADSP-218xL development tools, including the syntax highlight-
ing in the VisualDSP++ editor. This capability controls how the
development tools process inputs and generate outputs.
The ADSP-2189M EZ-KIT Lite
cost-effective method for initial evaluation of the powerful
ADSP-218xL DSP family architecture. The ADSP-2189M
EZ-KIT Lite includes a standalone ADSP-2189M DSP board
supported by an evaluation suite of VisualDSP++. With this
EZ-KIT Lite, users can learn about DSP hardware and software
development and evaluate potential applications of the
ADSP-218xL series. The ADSP-2189M EZ-KIT Lite provides an
evaluation suite of the VisualDSP++ development environment
with the C compiler, assembler, and linker. The size of the DSP
executable that can be built using the EZ-KIT Lite tools is lim-
ited to 8K words.
The EZ-KIT Lite includes the following features:
The ADSP-218x EZ-ICE
cost-effective method for engineers to develop and optimize
DSP systems, shortening product development cycles for faster
time-to-market. ADSP-218xL series members integrate on-chip
emulation support with a 14-pin ICE-Port
interface provides a simpler target board connection that
requires fewer mechanical clearance considerations than other
ADSP-2100 Family EZ-ICEs. ADSP-218xL series members need
not be removed from the target system when using the EZ-ICE,
nor are any adapters needed. Due to the small footprint of the
EZ-ICE connector, emulation can be supported in final board
designs.The EZ-ICE performs a full range of functions,
including:
