摘要：开发了一系列电子和机械部件，以简化现场海洋仪器电子系统的设计过程。该系列的基础是一个设计用于6英寸的卡架。I.D.压力情况下，和配套的CMOS计算机背板从IEEE-796（多总线）标准。利用该体系结构设计并实现了一套基于80 C86处理器的计算机板卡。该板包括80 C86 CPU、64 kbyte存储器模块、串行和并行I/O、时基和计数器以及16位A/D转换器。基于该板组的计算机在5V下以5 MHz CPU时钟工作时消耗375 mW，CPU时钟为7.5 mW，CPU时钟为STOP模式时为7.5 mW。除了计算机之外，卡架设计还可以适用于其他电子子系统的实现，包括模拟前端、大容量存储和电源控制系统。本报告描述了系统架构，给出了背板和机架的电子和机械规格，并记录了迄今为止设计的每个计算机板。（本报告的摘要部分已出现在IEEE海洋'86研讨会的会议记录中。关键词：中央处理器;输入输出处理;模数转换器。
Abstract : A family of electronic and mechanical components has been developed to streamline the process of designing electronic systems for in-situ oceanographic instrumentation. The basis for the family is a card rack designed to fit into 6-in. I.D. pressure cases, and a companion CMOS computer backplane derived from the IEEE-796 (Multibus) standard. A set of computer boards based on the 80C86 processor was designed and implemented using this architecture. The board set includes the 80C86 CPU, a 64 kbyte memory module, serial and parallel I/O, timebase and counter, and a 16-bit A/D converter. A computer based on this board set consumes 375 mW at 5V while operating with a 5 MHz CPU clock, and 7.5 mW with the CPU clock, and 7.5 mW with the CPU clock in STOP mode. In addition to computers, the card rack design can also be adapted to the implementation of other electronic subsystems, including analog front end, mass storage, and power control systems. This report describes the system architecture, gives electronic and mechanical specifications for the backplane and rack, and documents each of the computer boards designed to date.
