xilinx公司SoC器件Zynq-7000开发方案介绍_技术

The Zynq®-7000 All Programmable SoCs are available in -3, -2, and -1 speed grades, with -3 having the highest performance. Zynq-7000 device DC and AC characterisTIcs are specified in commercial, extended, and industrial temperature ranges. Except the operaTIng temperature range or unless otherwise noted, all the DC and AC electrical parameters are the same for a parTIcular speed grade (that is, the TIming characteristics of a -1 speed grade industrial device are the same as for a -1 speed grade commercial device). However, only selected speed grades and/or devices are available in the commercial, extended, or industrial temperature range.

All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters included are common to popular designs and typical applications

MicroZed™ is a low-cost development board based on the Xilinx Zynq®-7000 All Programmable SoC. Its unique design allows it to be used as both a stand-alone evaluation board for basic SoC experimentation, or combined with a carrier card as an embeddable system-on-module (SOM). MicroZed contains two I/O headers that provide connection to two I/O banks on the programmable logic (PL) side of the Zynq®-7000 AP SoC device. In stand-alone mode, these 100 PL I/O are inactive. When plugged into a carrier card, the I/O are accessible in a manner defined by the carrier card design.

MicroZedTM 是一款基于Xilinx Zynq®-7000 全可编程系统级芯片的低成本开发电路板。它的独特设计让其既可以被用作单独的基本SoC实验用的评估板，也可以与基板组合，用作嵌入式系统化模块(SOM)。 MicroZed 包括两个I/O 接头，在Zynq®-7000 AP SoC器件的可编程逻辑(PL) 端可以连接到两个I/O bank。在独立工作下，这100个P L I/O是闲置的。在插入基板后，这些I/O 可以按照基板设计所定义的方式访问。因此设计师可以从MicroZed独立工作开始，熟悉和了解这个平台；之后就可以很方便地通过增加一块现成的或用户设计的基板，来将其功能扩展为系统级模块。这种独立工作/SOM相结合的方法可以很快地将设计构思从概念转到投产，使MicroZed 成为基于SoC应用的理想平台。
