ADSP-2187L
–2–
The ADSP-2187L’s flexible architecture and comprehensive in-
struction set allow the processor to perform multiple operations
in parallel. In one processor cycle the ADSP-2187L can:
Generate the next program address
Fetch the next instruction
Perform one or two data moves
Update one or two data address pointers
Perform a computational operation
This takes place while the processor continues to:
Receive and transmit data through the two serial ports
Receive and/or transmit data through the internal DMA port
Receive and/or transmit data through the byte DMA port
Decrement timer
DEVELOPMENT SYSTEM
The ADSP-2100 Family Development Software, a complete set
of tools for software and hardware system development, sup-
ports the ADSP-2187L. The System Builder provides a high
level method for defining the architecture of systems under de-
velopment. The Assembler has an algebraic syntax that is easy
to program and debug. The Linker combines object files into an
executable file. The Simulator provides an interactive instruc-
tion-level simulation with a reconfigurable user interface to dis-
play different portions of the hardware environment.
A PROM Splitter generates PROM programmer compatible
files. The C Compiler, based on the Free Software Foundation’s
GNU C Compiler, generates ADSP-2187L assembly source
code. The source code debugger allows programs to be cor-
rected in the C environment. The Runtime Library includes over
100 ANSI-standard mathematical and DSP-specific functions.
The EZ-KIT Lite is a hardware/software kit offering a complete
development environment for the entire ADSP-21xx family: an
ADSP-218x based evaluation board with PC monitor software
plus Assembler, Linker, Simulator, and PROM Splitter soft-
ware. The ADSP-218x EZ-KIT Lite is a low cost, easy to use
hardware platform on which you can quickly get started with
your DSP software design. The EZ-KIT Lite includes the fol-
lowing features:
33 MHz ADSP-218x
Full 16-bit Stereo Audio I/O with AD1847 SoundPort
Codec
RS-232 Interface to PC with Windows 3.1 Control Software
EZ-ICE
Connector for Emulator Control
DSP Demo Programs
The ADSP-218x EZ-ICE Emulator aids in the hardware debug-
ging of ADSP-2187L system. The emulator consists of hard-
ware, host computer resident software and the target board
connector. The ADSP-2187L integrates on-chip emulation sup-
port with a 14-pin ICE-Port interface. This interface provides a
simpler target board connection requiring fewer mechanical
clearance considerations than other ADSP-2100 Family
EZ-ICEs. The ADSP-2187L device 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, emu-
lation can be supported in final board designs.
The EZ-ICE performs a full range of functions, including:
In-target operation
Up to 20 breakpoints
Single-step or full-speed operation
EZ-ICE and SoundPort are registered trademarks of Analog Devices, Inc.
Registers and memory values can be examined and altered
PC upload and download functions
Instruction-level emulation of program booting and execution
Complete assembly and disassembly of instructions
C source-level debugging
See “Designing An EZ-ICE-Compatible Target System” in the
ADSP-2100 Family EZ-Tools Manual
(ADSP-2181 sections) as
well as the Designing an EZ-ICE Compatible System section of
this data sheet for the exact specifications of the EZ-ICE target
board connector.
Additional Information
This data sheet provides a general overview of ADSP-2187L
functionality. For additional information on the architecture and
instruction set of the processor, see the
ADSP-2100 Family
User’s Manual, Third Edition
. For more information about the
development tools, refer to the ADSP-2100 Family Develop-
ment Tools Data Sheet.
ARCHITECTURE OVERVIEW
The ADSP-2187L instruction set provides flexible data moves
and multifunction (one or two data moves with a computation)
instructions. Every instruction can be executed in a single pro-
cessor cycle. The ADSP-2187L assembly language uses an alge-
braic syntax for ease of coding and readability. A comprehensive
set of development tools supports program development.

Figure 1. Functional Block Diagram
Figure 1 is an overall block diagram of the ADSP-2187L. The
processor contains three independent computational units: the
ALU, the multiplier/accumulator (MAC) and the shifter. The
computational units process 16-bit data directly and have provi-
sions to support multiprecision computations. The ALU per-
forms a standard set of arithmetic and logic operations; division
primitives are also supported. The MAC performs single-cycle
multiply, multiply/add and multiply/subtract operations with
40 bits of accumulation. The shifter performs logical and arith-
metic shifts, normalization, denormalization and derive expo-
nent operations.
The shifter can be used to efficiently implement numeric for-
mat control including multiword and block floating-point
representations.
The internal result (R) bus connects the computational units so
that the output of any unit may be the input of any unit on the
next cycle.
