fpga中经常用到ram和rom，更多人只会拿着乱用，不懂其真正原理，本文档详细说明了，fpga中rom和ram的时序和怎么使用！-fpga ram and is often used rom, holds more people will mess with, do not understand its true principles, this document details, fpga in the rom and ram timing and how to use!

The design shows how to use Dual port RAM in FPGA design

FPGA硬件中控制RAM存储，使用256x16的RAM-FPGA hardware to control the RAM memory, 256x16 of RAM

The Virtex™ series provides dedicated blocks of on-chip, true dual-read/write port synchronous RAM, with 4096 memory cells. Each port of the block SelectRAM+™ memory can be independently configured as a read/write port, a read port, o

此文档为fpga控制双口RAM的开发文档，讲解很细，易于上手.双口RAM是在1个SRAM存储器上具有两套完全独立的数据线、地址线和读写控制线，并允许两个独立的系统同时对其进行随机性访问的存储器，即共享式多端口存储器。-This document is controlled dual-port RAM fpga development documents, explain very small, easy to use. Dual-port RAM is an SRAM memory has tw
