dspblok™ 21469 User Manual Page 1
Overview
Danville Signal's dspblok™ family of products delivers the power of digital signal processing in a small 60mm
x 60mm form factor. Connections are brought out to standard 2mm dual row headers. The dspblok reduces
development costs, risk and time.
Danville’s dspblok DSP function modules are often incorporated directly into larger custom embedded
systems. By taking advantage of pretested signal processing modules, pc board layouts become simpler and
projects are completed quickly and cost effectively. Danville’s dspblok DSP Engines are largely pin
compatible. This allows your application to take advantages of new processor technology and extended
features in the future.
You can also create small standalone embedded applications by combining a dspblok DSP function module
with other dspblok modules. Embedded dspblok systems can be created by using a dspblok power supply
such as our dspblok ps-uart, and an I/O module, such as one of our dspblok ad96k family of audio data
converter boards. Each board is stacked via 2mm headers to create a low profile configuration where space is
at a premium. We also have combination power supply- I/O boards such as our dspblok a9238/48 high-
speed ADC boards for SDR applications.
Danville dspblok DSP Engines are the driving force behind many of Danville’s standalone products such as
our dspstak, dsprak, dspMusik and dspInstrument product lines.
dspblok™ Development Boards
All dspblok production modules have a companion developer’s version, which includes an Analog Devices’
EZ-KIT style debugger. These boards are physically larger (60mm x 115mm) to accommodate the debugger
but have a matching footprint to our production modules (60mm x 60mm). Once you have developed and
debugged your software, you can replace the debugger module (ICE version) with a lower cost, smaller
production module.
The dspblok “with ICE” versions include the free Visual DSP++ KIT license and are supported by the F LL
version. Depending on the complexity of your application, you may be able to create and support your
application without ever needing to purchase additional development tools. You can also use Analog
Devices’ CrossCore Embedded Studio.
dspblok™ 21469
The dspblok™ 21469 is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21469
SHARC DSP operating at 450 MHz with flash, EEProm and DDR2 SDRAM memory. An onboard switching
power supply supports the core voltage requirements of the DSP so that only 3.3V is required to power the
dspblok. The ADSP-21469 peripherals include SPORTS (8), SPI(2), TWI (I2C), ART, timers, PWMs, JTAG,
an 8 bit wide data bus and LINK ports(2). All of these peripherals are available via 2mm headers on the
dspblok.

Intended A dience
The dspblok 21469 requires an understanding of the Analog Devices’ ADSP-21469 and the associated tools
used for development. If the dspblok 21469 is going to be integrated into a larger hardware design, then it is
also assumed that the user is familiar with basic hardware design. In most cases, systems integrators, DSP
programmers and software engineers can create DSP embedded systems using our embedded dspblok
systems (or dspstak family) without the need for additional hardware design and manufacturing.
If you do not have a background with these skills, you may want to check out our web site
(http://www.danvillesignal.com) as well as the Analog Devices web site for links to useful references. Danville
engineers are also available to discuss your application.
Getting Started
Danville’s customer base is quite diverse. Our customers range from embedded systems hardware designers
to system integrators looking for complete turnkey solutions. We often work with embedded systems
engineers who may not have specific expertise in digital signal processing.
Regardless of your background, you will need the right tools. This means either Visual DSP++5.0 for SHARC
or CrossCore Embedded Studio for the software development along with either a dspblok 21469 with ICE or
an external ADI emulator.
Vis al DSP++5.0 vers s CrossCore Embedded St dio:
VisualDSP++ has been ADI’s DSP software environment for many years. In many ways, it has a similar look
and feel to Microsoft’s’ Visual Studio Tools. There are separate licenses for SHARC and Blackfin so customers
that need to support both families often need to buy two full licenses. In our view, the full version of
VisualDSP++ is expensive, about $3500 S. However, once you own VisualDSP++, you can continue
updating for free. Version 1.0 customers can now be using Version 5.0 without incurring any maintenance
charges. There are also KIT and TESTDRIVE licenses, which are free.
CrossCore Embedded Studio is ADI’s replacement for VisualDSP++. nlike VDSP++, it is Eclipse based. It
has a much lower entry cost: $1000 S. It will likely have upgrade costs as new processors are added. This
may not matter at all if you are not migrating to newer DSPs. CrossCore supports both Blackfin and SHARC
DSP with a single license. ADI offers a free 90 day TESTDRIVE version.

Em lation Options:
dspblok 21469+ICE:
Start your development with a dspblok 21469+ICE module. The “+ICE” version incorporates an ADI
Standalone Debug Agent. The debug agent is a SB bus powered device. It operates at full speed
(12Mb/s).
The dspblok 21469+ICE has the same footprint as a production dspblok except that the board is
much larger. This is necessary to fit the debug agent.
One of the advantages of the dspblok 21469+ICE is that it is supported by the VisualDSP++ KIT
license.
The KIT (free) version starts out as a F LL (TESTDRIVE) version but after 90 days requires that the
dspblok 21469+ICE is connected via the ADI debug agent. It will not connect to an ADI emulator,
simulator or support another SHARC DSP. The linker restricts a user program to 27306 words of
memory for code space with no restrictions for data space. The good news is that it can be used to
create bootable images (loader files) that can be used with the production dspblok 21469.
Depending on your situation, this may be all that you need.
You can also use the dspblok 21469+ICE with CrossCore Embedded Studio but you will need to buy
a license after 90 days.
dspblok 21469 with an external ADI ICE :
Start your development with a dspblok 21469 module. In this case, you will want to connect to the
dspblok 21469via an external Analog Devices emulator. Analog Devices offers two versions the SB-
ICE and the HP SB-ICE. We prefer the faster HP SB-ICE, which is up to 10 times faster and also
supports background telemetry. You will also need a Danville JTAG adapter kit (P/N A.08153),
which converts the Danville JTAG 2mm header to the larger ADI JTAG connector.
You will also need a F LL VisualDSP++ 5.0 or CrossCore Embedded Studio license after 90 days.
Development Boards:
If you are designing your own companion board, we strongly recommend that you use one of our existing
I/O boards and/or power supply boards as an initial development platform. Depending on your situation, this
could be a dspblok dev board, dspstak system, dspInstrument, or a combination of dspblok I/O and power
supply modules. Any of these components will give you a solid footing for development before you
incorporate the dspblok into your own target.
If you are laying out your own pc board, we can provide you with PCB footprints and schematic symbols
(Gerber & Altium Designer) to help you avoid simple mistakes.
Regardless of your situation, Danville engineers are available to help you with your application. We may
have solutions that are not yet on our web site. We also provide many solutions that are specifically tailored
to customer needs. Contact us about turnkey solutions.

Hardware Overview
The dspblok 21469 is a small module measuring 60mm x 60mm (2.36” x 2.36”). JH2 and JH4 – JH8 are
2mm male headers that are installed on the bottom side of the pc assembly. JH1 and JH3 are mounted on
the top side of the pc assembly. If mating 2mm female headers (4.3mm ht.) are used, the pc assembly will
be about ¼” above the mating pc board. This allows standard (0.250”) standoffs to be used with the corner
mounting holes if desired. The hole size is 2.3mm – suitable for 2-56 or M2 screws.

Power S pply
There are two power supply connections to the dspblok: DSP core (Vdd) and DSP I/O and Memory
(Vd+3.3). The DSP core supply may range from 3.3V to 5V. This is the input to an on-board switching
power supply that supplies 1.1V to the ADSP-21469. DO NOT use a higher voltage supply for the core
supply input (JH4-Vdd).
A single 3.3V supply is all that is required to power the dspblok 21469, but in some cases, a 5V supply may
be more convenient. The DSP I/O and Memory supply must be 3.3V.
For example, a product may already have a switching supply that converts directly to 3.3V. In this case, it
may be desirable to supply both the DSP core and the dspblok Vd+3.3 (I/O) from this supply.
Alternatively, a product might have a 5V supply (perhaps from an external power supply module). A simple
LDO fixed regulator could be used to create 3.3V from this supply. Most high-speed devices, including the
ADSP-21469, draw most of their power from their core supplies. In this scenario, it makes no sense to
power the dspblok core with 3.3V since the LDO would be dissipating the excess voltage as heat. If the I/O
requirements are modest, the power dissipation in the LDO might not be significant
Power consumption is largely a function of the temperature of (leakage current) of the ADSP-21469. It is also
a function of the core clock and the computation tasks that are being executed on the DSP. The highest
consumption occurs when the DSP is performing continuous floating point operations at maximum core
clock (450MHz) and at maximum temperature. Accessing external I/O such as the DRAM or other
peripherals consumes less power in the benchmarks that we have performed. The following table shows
power consumption measurements for a typical dspblok 21469 operating in a variety of configurations all at

room temperature. The Analog Devices’ ADSP-21467/ADSP-21469 SHARC Processor Data Sheet has an
excellent section on estimating power consumption of the DSP. Please note that the measurements do not
take into account the increase static current as temperature rises.
