Support for 6.144Gbps CPRI/OBSAI in a low-cost package optionHigh I/O bandwidth and 144GMACS DSP processing power in chip-scale packaging make the Kintex-7 70T FPGA highly effective for both front- and back-end ultrasound processing. Designers can deploy a fully programmable 128-channel ultrasound implementation that scales up to 196 or 256 channels for high-end cart solutions or down to 64 or 32 channels for hand-held solutions.
• 128-channel implementation in a modular set of five Kintex-7 70T FPGAs offers 44% lower power, 45% lower cost, and 57% smaller form factor compared to previous-generation FPGAs
• Kintex-7 70T FPGAs offer 144GMACS from 240 DSP slices (288GMACS for symmetric filters)
• Built-in support for eight PCI Express Gen1/Gen2 channels enables high-bandwidth interface to host system
• Chip-scale packaging for small form factor

Kintex-7 FPGAs enable cost-effective, low-power bridging of the serial digital interface (SDI) protocol onto IP technology for long-distance WAN transport to link local studios/live events, broadcast facilities, and satellite uplink stations using standard IP networks.
• Reduce power by 64% and reduce cost by 85% with a single XC7K160T FPGA implementation of a 12x 3G-SDI over 4x10GbE bridge compared to the equivalent function implemented in two Virtex-6 XC6L130T devices
• Reduce cost further with high-bandwidth interfaces that shrink BOM: 72-bit x 1,600Mbps DDR3 memory interface capability enables a single memory buffer that would require two or four memory buffers in previous-generation FPGAs.

如何提高基于FPGA的原型的可视性采用基于现场可编程门阵列(FPGA)的原型的验证团队面临的最大挑战之一在于当原型系统未能发挥期望的性能时了解原型系统的内部行为。分析和调试这些设计的一个关键因素是难以观察内部信号。目前的顶级FPGA在 基于C8051F020和USB的OLED控制系统设计1 引言 与传统的液晶显示屏相比，OLED显示模块具有高亮度、高对比度、宽视角、响应速度快、功耗低等特点。因此，随着电子产品高度集成化的发展，OLED显示模块在移动终端、工业控制、便携式电子产品等领域 [DCDC]一个电击器的升压部分求助 本帖最后由 yangff 于 2016-11-7 11:58 编辑 简单的说就是x宝上很常见的那种用来做羞羞的事情的电击器。 （也有叫做经络电击理疗仪什么的，都是一个东西……）它里面的升压部分，结构上是一个类似boost的结构。 能产生100~200多v的电压只不过并不需要连续的高压输出，所以只是震荡升压对电容充电再放电的过程。 然后我想改造一下它的控制方式，于是我做了两个尝试：1. 在上面引了几条线出来，用自己的arduino来产生pwm波形和控制信号。 这可以让它
