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.
