Introducing dspstak™ DSP Engines and I/O Modules

Simplify your DSP-based embedded applications with dspstak™ DSP Engines and Signal Conditioning / Data Conversion I/O Modules.

p_21262sx_c96k44_r_270

Each dspstak™ consists of two or more modules:

  1. A DSP engine
  2. Signal conditioning / data conversion I/O Module(s)

Danville Signal's dspstak™ Engines are available for latest Analog Devices SHARC® family processors. The modules generally consist of a DSP processor, memory, power supplies and standard digital I/O such as RS-232 and USB.

The I/O Modules may include signal conditioning electronics, A/D and/or D/A converters, audio transceivers, unique connectors and a plethora of other special front end requirements.

Since the I/O dspstak™ module is separate from the DSP module, custom interfaces can be created quickly and inexpensively.

Painless Development!

Danville has several platforms of dspstak DSP Engines. Each platform is supported by a dspstak DSP Engine with ICE. The ICE is a licensed version of Analog Devices' EZ-KIT Lite debugger and is fully supported by Analog Devices Visual DSP++. This means that you can treat a dspstak just like a EZ-KIT Lite development board and then move directly to a production version of the same board.

The dspstak DSP Engine with ICE is supported by a free KIT license of Visual DSP++ with exactly the same functionality as an Analog Devices EZ-KIT. All dspstak DSP Engines can also take advantage of the full featured Visual DSP++ tools and the Analog Devices HPUSB & USB emulators. We resell these tools if you are interested.

All dspstak DSP Engines include flash memory to store program code. Bootable program code can be uploaded into the flash by either USB or RS-232 without the need for any special programming tools.

dspstak™ 21262sx DSP board is a high performance digital signal processing engine based on the Analog Devices ADSP-21262 SHARC® DSP. This DSP supports 32 bit fixed point and 32/40 bit floating point formats with SIMD instructions running at up to 200 MHz. This translates to a peak computation rate of 1.2 GFLOPS.

The ADSP-21262 includes six independent serial ports (SPORTs) and a SPI port.

The dspstak™ 21262sx Interconnect Port supports the complete DAI interface, SPI, general I/O, clocks and power connections.

The dspstak™ 21262sx also includes USB and RS-232 ports for easy interfacing to the outside world. It has a JTAG interface to facilitate program development.


Optional Accessories for the dspstak™ 21262sx

dspstak 21262sx SRAM Expansion Board

The dspstak 21262sx SRAM board provides 3 Megabytes of external SRAM for data memory expansion. This memory is useful for creating large delay lines that are commonly needed for room correction, inverse filtering, echo cancellation and reverberation algorithms.

JTAG Adapterdspstak DSP JTAG Adapter

Danville JTAG connectors are smaller than the standard ADI recommended JTAG header. The Danville DSP JTAG Adapter converts the Danville JTAG header used to the Analog Devices JTAG connector standard.
