Although earlier systems had tended towards array arrangements that had the storage cells connected in parallel on one or more axes, the new system employed series connections along two axes. This new arrangement has several design and performance advantages compared to previous systems. The original paper described the basic approach and some of the earlier work which included the design of array cross sections and the associated driving and sensing circuits. Since that time one version of the system has been operational in two IBM 7030 systems, and a 16-word, fully-populated, higher-speed laboratory model was built and reported. The present paper describes the engineering considerations used in the design of a larger and faster memory employing the basic techniques.","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":"133442130","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}

These memories allow simultaneous comparison of all stored data to external data. Data may be read from, or written into, comparing words. These memories, acting as peripheral devices to conventional computers, have been studied for application to various tasks described in references 1 and 2. The concept of \"associative processing,\" i.e., simultaneous transformation of many stored data by associative means, has been described previously. This processing mode showed promise in a variety of tasks, but was not efficient when peripherally controlled by a conventional machine. Novel machine organizations were required to fully exploit the potential of these techniques for solving poorly structured nonnumeric problems, at which present-day machines are not efficient.","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":"115812089","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}

Furthermore, the size and speed requirements increase. An early memory, suitable for use as a scratchpad, was described by H. Amemiya, R. L. Pryor, and T. R. Mayhew. This memory used two ferrite cores per bit and had a read/regenerate cycle time of 200 nanoseconds. More recently, a 64-word by 20-bit thin magnetic film memory was described by G. J. Ammon and C. Neitzert. This memory had a read/regenerate cycle time of 125 nanoseconds and its speed was limited primarily by the electronic circuitry. A number of other memories and memory designs, suitable for use as scratchpads, have been reported in the literature. Future need for a 256 to 1,024 word memory having a cycle time of 50 nanoseconds has been indicated. A project was therefore initiated to study the feasibility of such a system.","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":"120884894","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}

A large number of active programs requiring various services are present in the system and their current status and required service are recorded. When some component of the system becomes available, e.g., processor, memory space, peripheral device, it is assigned to the active job of highest priority that requires this service. The important concept is that no component of the system belongs to any program but rather provides a service and then goes on to service another program. The main function of the executive scheduling program is to keep track of the services required by programs and to schedule the services when equipment becomes available.","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":"126798763","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 circuit might be a code converter, where the A inputs are an input code (for example, the machine-code of an alphanumeric character); and the B outputs are an output code (for example, the pattern of signals required for a display of that character). The circuit might be a table look-up device, where, for example, the input variables are a code for the numeric value of a given argument, and the output variables are a code for the value of some function of that argument. Finally, the circuit might be considered as a memory, with fixed information stored, where the A input bits are an address, and the B output bits are the word stored at that address. It is called a \"read-only\" or \"fixed\" memory if the information stored is not alterable at electronic speeds.","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":"126598001","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}
