Source text progresses through a linear array of 32 cells each cell capable of holding one character. With all cells operating in parallel, character subsequences in the source stream can be compared with character strings in any one of 16 registers associated with the cellular array. Various modules associated with the array are used to aid the query resolution process. The overall design emphasizes speed of execution and versatility of operation.","PeriodicalId":328859,"journal":{"name":"Computer Architecture Workshop","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116837007","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}

Using rings as a basic building block, we have constructed different intercell communication networks. The capacity of the communication network have been analyzed under the workload of relational algebra operations. A k-dimensional network of intersecting rings, each of 2 or 3 cells have been found to give the highest processing capacity per cell in the network. Here k is log 2 C, where C is the total number of cells. A simple wiring scheme for k-dimensional network of 2 cells per ring has been presented. For this type of network, we have also described the routing logic, and given an estimate of the queueing delay.","PeriodicalId":328859,"journal":{"name":"Computer Architecture Workshop","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125773175","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}

Bisiani","doi":"10.1145/647003.711861","DOIUrl":"https://doi.org/10.1145/647003.711861","url":null,"abstract":"Efficiently storing and retrieving data has always been one of the major problems in computer technology. Until recently there has been more interest for the technology of storing and retrieving data in mass memory than for the problem of accessing data in main memory. Semiconductor technology improvements have lowered main memory cost and increased speed, therefore opening new application areas (e.g. image and speech understanding, graphics) to low cost systems. Some of the tasks in these areas are data intensive and require complex data structures. In these cases, most of the computing power is used to access data rather than to perform operations on them. The performance of such applications can be improved if the memories are tailored to the data structures they contain and to the access operations that can be performed on those data structures. The paper describes an architecture designed to explore the advantages offered by tailored, intelligent memories. The architecture has been implemented and tested on the Harpy speech understanding system. The implementation has been measured and the results are reported in the paper.","PeriodicalId":328859,"journal":{"name":"Computer Architecture Workshop","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130059055","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 two-way cable television provided a model for investigating the possibilities of new screen-orientated, interactive systems for large numbers of subscribers using alpha-numerics, graphics, motion-pictures, and sound. One of the most important research aspects proved to be the construction of a computer control centre which would cater for this type of hybrid information system. At present a laboratory model of such a control centre is being developed by the Heinrich-Hertz-Institute in collaboration with the Computer Industry. This model is based on a mini-computer multi-processor system.","PeriodicalId":328859,"journal":{"name":"Computer Architecture Workshop","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115512853","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}
