，DMA方式就是在一定时间段内，由DMA控制器取代CPU，获得总线控制权，来实现内存与外设或者内存的不同区域之间大量数据的快速传送。-, DMA mode is in a certain period of time, by the DMA controller to replace the CPU, access to the bus control, to achieve the memory and peripherals or memory large amounts of data b

Abstruct- We describe novel interleaver and deinterleaver architectures that support bandwidth efficient memory access for decoders of turbo-like codes that are used in conjunction with high order modulations. The presentation focuses on a deco

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
