继1977年DEC(Digital Equipment Corp-oration)发表的16位微型计算机LSI—11/2后,今年(79)3月又发表了微型计算机LSI—11/23,该机与微型机LSI—11/2在软件方面有互换性,其速度约快2—4倍。规模与小型计算机PDP—11系列的中型机PDP11/34的硬件相等,在性能方面大大超过了微型计算机的范围。不仅如此,而在价格方面与微型计算机相同。LSI—11/23与LSI—11/2的不同点、特征就在于存储器的设计技术。本文以存储器管理为中心加以详述硬件结构。因此,存储器可扩展到256K
Following the 16-bit microcomputer LSI-11/2 from DEC Digital Equipment Corp. in 1977, it released the LSI-11/23 in March this year (March 79) 2 in the software interchangeability, its speed is about 2-4 times faster. Equally to the hardware of the PDP11 / 34 medium-sized PDP11 / 34, the Small Computer PDP-11 is significantly larger in performance than the microcomputer. Not only that, but the same price with the microcomputer. The difference between LSI-11/23 and LSI-11/2 is characterized by memory design techniques. This article focuses on memory management to detail the hardware structure. Therefore, the memory can be expanded to 256K
