目前常用的微机图象显示设备中的帧存储板一般只有两个接口,如CROMEMCO Ⅲ微机图显设备中的48KB双口帧存储板(简称48KBTP),其一个接口用于与微机S-100总线(以下均称为总线)进行数据交换,一般用这个通道把图象信息写入帧存储板。另一接口与显示接口板(简称SDI,和显示器相连)相通,SDI反复地从48KBTP读取图象信息送往显示。利用这套图象显示系统,我们可以开发一个将摄象系统所摄图象进行实时显示,实时存储(一般存储在大容量的硬盘上)和数据处理的数字化图象微机系统。为了保证外部设备传输
Currently commonly used computer graphics display device in the frame memory board generally only two interfaces, such as CROMEMCO Ⅲ microcomputer graphics device in the 48KB dual-port frame memory board (referred to as 48KBTP), an interface for use with the microcomputer S-100 bus (Hereinafter referred to as bus) for data exchange, the general use of this channel to write image information frame memory board. Another interface with the display interface board (referred to as SDI, connected with the monitor) connected, SDI repeatedly read image information from the 48KBTP sent to the display. Using this image display system, we can develop a digital image microcomputer system that displays the images taken by the camera system in real time, real-time storage (usually stored on a large-capacity hard disk drive) and data processing. In order to ensure the transmission of external equipment
