ADSP-2186M
–3–
GENERAL DESCRIPTION
The ADSP-2186M is a single-chip microcomputer optimized
for digital signal processing (DSP) and other high-speed numeric
processing applications.
The ADSP-2186M combines the ADSP-2100 family base archi-
tecture (three computational units, data address generators, and
a program sequencer) with two serial ports, a 16-bit internal DMA
port, a byte DMA port, a programmable timer, Flag I/O, exten-
sive interrupt capabilities, and on-chip program and data memory.
The ADSP-2186M integrates 40K bytes of on-chip memory
configured as 8K words (24-bit) of program RAM, and 8K
words (16-bit) of data RAM. Power-down circuitry is also pro-
vided to meet the low power needs of battery-operated portable
equipment. The ADSP-2186M is available in a 100-lead LQFP
package and 144 Ball Mini-BGA.
In addition, the ADSP-2186M supports new instructions, which
include bit manipulations—bit set, bit clear, bit toggle, bit test—
new ALU constants, new multiplication instruction (
× squared),
biased rounding, result-free ALU operations, I/O memory trans-
fers, and global interrupt masking, for increased flexibility.
Fabricated in a high-speed, low-power, CMOS process, the
ADSP-2186M operates with a 13.3 ns instruction cycle time.
Every instruction can execute in a single processor cycle.
The ADSP-2186M’s flexible architecture and comprehensive
instruction set allow the processor to perform multiple opera-
tions in parallel. In one processor cycle, the ADSP-2186M 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, supports
the ADSP-2186M. 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.
The EZ-KIT Lite is a hardware/software kit offering a complete
evaluation environment for the ADSP-218x family: an ADSP-
2189M-based evaluation board with PC monitor software plus
assembler, linker, simulator, and PROM splitter software. The
ADSP-2189M 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 VisualDSP
The ADSP-218x EZ-ICE
Emulator aids in the hardware
debugging of an ADSP-2186M system. The ADSP-2186M
integrates on-chip emulation support with a 14-pin ICE-Port
interface. This interface provides a simpler target board connec-
tion that requires fewer mechanical clearance considerations
than other ADSP-2100 Family EZ-ICEs. The ADSP-2186M
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 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-2186M
functionality. For additional information on the architecture and
instruction set of the processor, refer to the ADSP-2100 Family
User’s Manual. For more information about the development
tools, refer to the ADSP-2100 Family Development Tools
data sheet.
