In view of this a design was undertaken which would be inherently faster, and inherently less expensive in the large sizes. Other significant inputs to the design approach chosen was that electronics, that is semiconductors, were becoming less expensive; also, to operate at the higher speeds smaller cores must be used. Since it is progressively more difficult to put additional wires through these smaller cores, system approaches using fewer wires through the core were studied.","PeriodicalId":143723,"journal":{"name":"AFIPS '65 (Fall, part I)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115728369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, mathematical models make up the heart of many engineering disciplines. The rapid increase in scientific knowledge has brought about a staggering proliferation of technological applications. In order to equip students for this exploding technical environment, engineering colleges have turned to emphasizing fundamentals. It is physically impossible to include even a representative sampling-in-depth of today's technological developments without further crowding the already overburdened curricula. This crowding is due not so much to the new ideas the newer scientific applications require, but rather to the inordinate number of details and refinements they engender.","PeriodicalId":143723,"journal":{"name":"AFIPS '65 (Fall, part I)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122322792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The discussion is further confined to significant factors affecting circuit decisions in a high volume commercial/industrial environment. Laboratory curiosities operating at absolute maximum speeds are not considered in view of the extremely distorted economics associated with experimental technologies. The factors under discussion are technology considerations, economic considerations, logic arrays, power dissipation, and packaging media constraints. The discussion is not intended to be a gross prediction of future practice, but rather a snapshot of today's design considerations imposed by present technology and Mother Nature's rather rigid philosophy concerning the speed of light. Since the transmission time through the interconnecting media is significant when compared to propagation delay time of the logic device, the physical size of the system has some bearing on the definition of high speed. This discussion is concerned with relatively large organizations such that a propagation delay time of 2 to 5 nanoseconds may be considered high speed. More dramatic speed improvements may come with machine organizations which consume large amounts of circuits. These organizations are now becoming feasible due to increased reliability and the availability of low cost devices through the semiconductor industry.","PeriodicalId":143723,"journal":{"name":"AFIPS '65 (Fall, part I)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122002258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under this monitor, the typical job enters the system through a 1004 card reader, queues at a section of one drum designated the Input/Output buffer, is processed by the main frame using the drums for scratch storage and systems routines, occupies I/O drum buffer area for storage of output, and is printed on the originating 1004 system. The monitor \"steals\" cycles from the main frame to control the flow of data between the 1004's and the drum I/O buffer.
