ADSP-2186
–2–
REV. B
Fabricated in a high speed, double metal, low power, CMOS
process, the ADSP-2186 operates with a 25 ns instruction cycle
time. Every instruction can execute in a single processor cycle.
The ADSP-2186’s flexible architecture and comprehensive
instruction set allow the processor to perform multiple opera-
tions in parallel. In one processor cycle the ADSP-2186 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-2186. The System Builder provides a high level
method for defining the architecture of systems under develop-
ment. 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 instruction-
level simulation with a reconfigurable user interface to display
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-2186 assembly source code.
The source code debugger allows programs to be corrected 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 ADSP-218x family: an ADSP-
218x-based evaluation board with PC monitor software plus
Assembler, Linker, Simulator and PROM Splitter software. 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 following features:
75 MHz ADSP-2189M
Full 16-bit Stereo Audio I/O with AD73322 Codec
RS-232 Interface
EZ-ICE Connector for Emulator Control
DSP Demo Programs
Evaluation Suite of Visual DSP
The ADSP-218x EZ-ICE Emulator aids in the hardware debug-
ging of an ADSP-2186 system. The emulator consists of hard-
ware, host computer resident software, and the target board
connector. The ADSP-2186 integrates on-chip emulation sup-
port with a 14-pin ICE-Port interface. This interface provides a
simpler target board connection that requires fewer mechanical
clearance considerations than other ADSP-2100 Family EZ-
ICEs. The ADSP-2186 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,
emulation 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
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 Target Board Connector for EZ-ICE Probe 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-2186
functionality. For additional information on the architecture and
instruction set of the processor, refer to the ADSP-218x DSP
Hardware Reference. For more information about the develop-
ment tools, refer to the ADSP-2100 Family Development Tools
Data Sheet.
ARCHITECTURE OVERVIEW
The ADSP-2186 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
processor cycle. The ADSP-2186 assembly language uses an
algebraic syntax for ease of coding and readability. A compre-
hensive set of development tools supports program development.

Figure 1. Block Diagram
Figure 1 is an overall block diagram of the ADSP-2186. 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
format control including multiword and block floating-point
representations.
