Virtex-5 SXT

Virtex-5 FPGA



Virtex®-5 SXT FPGA针对DSP和存储器密集型应用进行了优化,是世界上首款采用1.0V三栅极氧化层工艺技术制造而成的65nm系列的引脚兼容成员。针对具有低功耗串行连接功能的DSP和存储器密集型应用进行了优化,整合了增强型DSP模块,可以实现并行处理、最高的存储器-逻辑比和用于实现最高I/O带宽的低功耗串行收发器。
Virtex-5 SXT平台为无线WIMAX以及监控和广播等高分辨率视频等领域中的高性能数字信号处理应用提供了最高的DSP模块和逻辑资源比。增强的DSP逻辑片(DSP48E)包括一个25x18位乘法器、一个48位第二级累加和算法运算单元以及一个可扩展到96位的48位输出。更宽的数据路径和输出可支持更广泛的动态范围和更高的精度,同时 还优化了对单精度浮点运算的支持,而所消耗的资源只有90nm FPGA的一半。
