构成现代计算机系统的各种逻辑装置的单元几乎全集成化了。而这些集成电路也由过去的小规模发展到中规模、大规模,其集成度一直是在增加的。另一方面,组装集成电路的印制板也变为层数多于两面印制板的多层结构,与此同时,研制了区别连接电路用的细通孔和组装一般元件用的通孔的技术,组装密度现在可以是过去的1.6倍左右。各种逻辑集成电路的低功耗已经发展到现在较好的程度,即使是这样,由于集成电路集成度的增加以及各逻辑标准件组装密度的增大,导致单位体积平均功耗的增长。本文介绍对计算机系统、特别是小型计算机系统的电源装置在功能和性能等方面的要求。
The units of the various logic devices that make up modern computer systems are almost fully integrated. These integrated circuits have also evolved from small-scale to medium-scale and large-scale in the past, and their integration has been on the increase. On the other hand, the printed circuit board on which the integrated circuit is mounted has also become a multilayer structure having more layers than the double-sided printed board. At the same time, fine vias for distinguishing connecting circuits and through-holes for assembling general components have been developed Technology, assembly density can now be about 1.6 times the past. The low power consumption of various logic integrated circuits has been developed to a better level nowadays. Even so, the average power consumption per unit volume increases due to the increased integration of integrated circuits and the increase in the assembly density of logic standards. This article describes the computer system, especially the small computer system power devices in terms of functionality and performance requirements.
