Virtex-5 SXT Devices
Virtex-4 SX Devices
Spartan-3A DSP Devices

Virtex-DSP and Spartan-DSP Series

The Virtex DSP and Spartan DSP series provide the range of devices with price, performance, power efficiency, bandwidth and I/O to satisfy a broad spectrum of application requirements. These reprogrammable DSP devices can function as a replacement for multiple DSP processors, ASSP, ASIC, or as complementary co-processor to DSP processor in your DSP applications.

Virtex DSP device architectures offer optimum DSP fabric to exploit maximum DSP performance potential. Spartan DSP devices offer price/performance benefits.

Virtex-4 SX Devices

These devices also deliver high performance for performance centric or multi-channel applications for DSP designs that demand a high ratio of DSP to logic. They offer more DSP algorithms and higher levels of DSP integration than were available in prior programmable devices, while delivering low power consumption and efficient silicon utilization. Up to 512 XtremeDSP DSP48 slices operating at 500 MHz help you solve complex challenges such as implementing hundreds of IF-to-baseband down-conversion channels.

Spartan-3A DSP Devices – Breakthrough Price/Performance

The Spartan-3A DSP device efficiently balances three critical values — price, performance, and power consumption — for a host of applications.

It targets price and power-sensitive applications such as digital front-end (DFE) and baseband solutions in a single-channel pico-cell wireless base station, military mobile software-defined radios (SDRs), ultrasound systems, driver assistance/media systems, HD video and Smart IP cameras:
