Danville Signal - Your Partner for SHARC-based DSP Boards, Hardware and Systems

The dspstak™ 21469 family of DSP boards are high performance digital signal processing engines based on Analog Devices fourth generation ADSP-21469 SHARC® DSP. This SHARC supports 32 bit fixed point and 32/40 bit floating point formats with SIMD instructions running at up to 450 MHz. This translates to a peak computation rate of 2.7 GFLOPS.

The core signal processing engine of the dspstak 21469 is a dspblok 21469 module. This module includes a 1Gb DDR2 SDRAM, flash and eprom memory. Since the core is dspblok based, it is possible to create other dspstak versions with the same base. You may wish to review the dspblok™ product page for more information.

The ADSP-21469 has very flexible peripherals including up to eight independent serial ports (SPORTs), two SPI ports, TWI (I2C), and two UARTs. The dspstak™ Interconnect Port supports the complete DAI interface, SPI, general I/O, clocks and power connections.

The dspstak 21469 includes an RS-232 interface and a high speed USB 2.0 interface. There is driver support for most popular OS's including Windows, Linux and Mac. The USB drivers can emulate a COM port. You can use a simple terminal program to communicate with the dspstak 21469 including uploading application code to flash. There is also a Windows DLL for integration into your application.

The dspstak 21469 with ICE version uses a dspblok 21469+ICE module which includes a built-in Analog Devices' EZ-KIT Lite debugger. It is supported by Analog Devices Visual DSP++ 5.0. You can use the debugger with either an EZ-Kit license (free) or a full Visual DSP license. You can also connect an Analog Devices HPICE via JTAG connections.

Optional Accessories for the dspstak 21469 Family

dspstak 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.
