在数字图象处理系统中,常常需要把整幅数字图象矩阵的信息或数字图象矩阵中的某一行、某一帧的信息存贮起来.因此图象存贮体是数字图象处理系统中不可缺少的关键部件之一.存贮数字图象信息的方法是很多的.一般有外存和内存,外存贮体有磁鼓、磁带及磁盘等.内存贮体有磁芯存贮体及半导体存贮器之分.在图象处理系统的设备中都采用内存贮体.由于半导体存贮器体积小、速度快、使用方便、价格比磁芯存贮体便宜.因此近年来都采用半导体存贮器.这里我们介绍一个应用MB8114半导体静态存贮器所设计的图象存贮体.它的容量为256×256×12位,写入速度取决于所连接的计算机速度,而读取速度是每一象点为0.2微秒.
In a digital image processing system, it is often necessary to store the information of the entire digital image matrix or information of a certain frame or frame in the digital image matrix, so that the image memory is a digital image processing system Is one of the indispensable key components.Method for storing digital image information is very much.It usually has external memory and memory, the external memory has a drum, magnetic tape and disk, etc. Memory storage core storage Body and semiconductor memory points in the image processing system equipment are used in the memory storage.Since the semiconductor memory is small, fast, easy to use, the price cheaper than the core storage, so in recent years Use semiconductor memory. Here we introduce a MB8114 semiconductor static memory designed image storage. Its capacity of 256 × 256 × 12-bit, write speed depends on the speed of the connected computer, and Read speed is 0.2 microseconds for each pixel.
