Using this foundation, examples of existing cache memory systems are detailed and compared.\u0000 The second presentation discusses a programmable cache memory architecture. In this architecture, intelligence is added to the cache to direct the activity between the cache and the main memory. Also to be described are heuristics for programming the cache which allow the additional power to be exploited.\u0000 The third presentation deals with innovations involving systems where the cache memory is not used as a simple high speed buffer for main memory. A straight forward example of this appears in IBM's Translation Lookaside Buffer on 370s with dynamic address translation hardware. Other examples are to be described include a cache system for the activation stack of a block structured language, a cache system to store subexpressions for an expression oriented architecture, and a multiprocessor architecture that relies on two levels of cache.","PeriodicalId":321698,"journal":{"name":"ACM '82","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123764867","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}

Recently, new methods have been presented called optimistic methods. These methods are well suited in situations where the likelihood of conflicting actions is rather small.

Therefore what is really needed are methods which combine the benefits of optimistic methods and locking.

It is no longer satisfactory to merely have a separate, supportive computer center configured on a centralized basis with its hardware/software/database constituents designed for and situated in a tightly controlled, remote computer room, accessible only to well-trained staff. Instead a modern-day office demands distributed processing and access for potentially all of its employees. It is forcing us to consider the networking of a number of heterogeneous types of computers and terminals with various kinds of nonspecialist users who need or want suitable access from their personal workstations. This precipitates not only “distribution” of hardware, but also systems software, applications software, databases, network control, access security, and more.\u0000 Indeed, if we define an automated office (or a computer-based office system) to be an organizational/technological entity which encompasses a set of resources (computer hardware, software, databases, communications equipment, people, etc.) working in some specified pattern(s) of interconnection, interdependency or relation toward the accomplishment of one or more organizational objectives, we have quite a job on our hands in terms of applied research which can support the design of such a system. Not only must its low-level functioning with respect to its component resources be addressed; attention must also be paid to putting those pieces together into an effectively operating complete system. The latter requires research with a global view and with abilities to conceptualize, model, analyze, synthesize and integrate the various component parts and related considerations toward creating a unified, harmonious whole.","PeriodicalId":321698,"journal":{"name":"ACM '82","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121146678","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}

This survey analyzes eight major operating systems.
