SUMMARY DESCRIPTION
The DSM2190F4 is a system memory device for
use with the Analog Devices ADSP-2191 DSP.
DSM means Digital signal processor System
Memory. A DSM device brings In-System Pro-
grammable (ISP) Flash memory, parameter stor-
age, programmable logic, and additional I/O to
DSP systems. The result is a simple and flexible
two-chip solution for DSP designs. DSM devices
provide the flexibility of Flash memory and smart
JTAG programming techniques for both manufac-
turing and the field. On-chip integrated memory
decode logic makes it easy to map dual banks of
Flash memory to the ADSP-2191 in a variety of
ways for bootloading, code execution, data re-
cording, code swapping, and parameter storage.
JTAG ISP reduces development time, simplifies
manufacturing flow, and lowers the cost of field up-
grades. The JTAG ISP interface eliminates the
need for sockets and pre-programmed memory
and logic devices. For manufacturing, end prod-
ucts may be assembled with a blank DSM device
soldered to the circuit board and programmed at
the end of the manufacturing line in 10 to 25 sec-
onds with no involvement of the DSP. This allows
efficient means to test product and manage inven-
tory by rapidly programming test code, then appli-
cation
requirements (Just-In Time inventory). Additional-
ly, JTAG ISP reduces development time by turning
fast iterations of DSP code in the lab. Code up-
dates in the field require no disassembly of prod-
uct. The FlashLINK
TM
JTAG programming cable
costs $59 USD and plugs into any PC or note-
book parallel port.
In addition to ISP Flash memory, DSM devices
add programmable logic (PLD) and up to 16 con-
figurable I/O pins to the DSP system. The state of
each I/O pin can be driven by DSP software or
PLD logic. PLD and I/O configuration are program-
mable by JTAG ISP, just like the Flash memory.
The PLD consists of more than 3000 gates and
has 16 macro cell registers. Common uses for the
PLD include chip selects for external devices,
state-machines, simple shifters and counters, key-
pad and control panel interfaces, clock dividers,
handshake delay, multiplexers, etc. This elimi-
nates the need for small external PLDs and logic
devices. Configuration of PLD, I/O, and Flash
memory mapping are easily entered in a point-
and-click environment using the software develop-
ment tool, PSDsoft Express
TM
. This software is
available at no charge from www.st.com/psm.
