Optimized for ultra-high performance signal processing, Virtex®-4 SX FPGAs are a pin-compatible member of the world’s first 90nm family fabricated in 1.2v, triple-oxide process technology.
Virtex-4QV SX FPGAs Benefits
Enhanced clocking for high performance
Minimize clock jitter, skew, and duty cycle distortion
Easy to place and route large designs with abundant, fully flexible clock resources that eliminate constraints encountered in previous generation FPGAs
Easy to build source-synchronous interfaces with built-in circuitry for aligning clock and data signals at physical interfaces with ChipSync™ technology
Facilitate DSP algorithms and high levels of DSP integration with XtremeDSP™ slices
Offers the cost-effective implementation of ultra-high performance DSP functionality, with the highest ratio of XtremeDSP slices Up to 512 slices delivering up to 256 GMACS performance The 500 MHz XtremeDSP slice delivers unmatched versatility, efficiency, and performance Configure each XtremeDSP slice for over 40 DSP functions, such as multiply-accumulate, multiply, addition, and multiplexing Reduce DSP power consumption by 86% (57μW/MHz) and save precious logic resources for other tasks Cascade multiple XtremeDSP slices at full system speed to build complex filters and multi-precision functions
Ultimate design protection
Software-based bitstream encryption and on-chip bitstream decryption logic with dedicated memory for storing the 256-bit encryption key Generate the encryption key and encrypted bitstream using Xilinx ISE® software Virtex-4 FPGAs store the encryption key internally in dedicated RAM, back ed up by a small externally connected battery (typical life 20+ years).
