Emulation 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 USB 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 Vi+ KIT
license.
The KIT (free) version starts out as a FULL (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 USB-
ICE and the HPUSB-ICE. We prefer the faster HPUSB-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 FULL Vi+ 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.
