摘要
本文介绍了一种新的图象存储系统,它支持对图象矩阵的任意位置进行p×q块方式存取,该图象存储系统具有pq个存储模块,采用新提出的存储模块分配函数和地址分配函数。其地址计算电路极其简单,仅含3个加法器和pq个4:1多路器,能够同时为pq个存储模块计算地址;数据分布电路只有一个,用来完成读出和写入时数据在数据寄存器和存储模块之间的分布。与同类存储系统比较,该存储系统高效、简单。
A novel image memory system is proposd,which permits p×q block access at any location of the image array.The memory system,which is based on the new memory module assignment function and address assignment function,consists of pq memory modules.The address calculating circuit is very simple and consists of three adders and pq 4:1multiplexers,which calculates pq addresses for the pq memory modules in parallel.Only one data routing circuit is needed in the proposed memory system. which routes the data efficiently between the data register and the memory modules both in the write cycle and in the read cycle.Thus,the proposed memory system is more efficient and simple than other memory systems which permit p×q block access.
