Teller, Kenner, and Snir 1161 proposed locating TLBs at memory. Using trace-driven simulations, Teller and Gottlieb 1151 compared the performance of memory-based TLBs with that of conventional processor-based TLBs. Their results indicate that memory-based TLBs can outperform processor-based TLBs in uniprogrammed multiprocessors, provided that memory is partitioned into equal-size clusters to which virtual-to-physical page mappings are fured (called paging arenas) and the number of paging arenas (M) increases with the number of processors (N). We extend Teller and Gottlieb's study by simulating multiprogrammed memory-based TLB systems with M = 2\"', m=O, ..., 3 and larger-size TLBs. Our results agree with those of [I51 and indicate that for memory-based TLB systems, as M increases with N , performance improves, while the percentage of improvement &creases. We also show that comparable performance improvements can be attained by systems with one paging arena and larger memory-based TLBs. Unlike processor-based TLBs, the size of memory-based TLBs is not limited by processor chip size.","PeriodicalId":203232,"journal":{"name":"Proceeding of 13th IEEE Annual International Phoenix Conference on Computers and Communications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131873104","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}

We now have standardized low bit rate video compression codes such as CCITT H.261, and also have low cost network access such as Ethernet, frame-relay, and switched megabit data service (SMDS). To facilitate research for cost-effective video communications over packet switching networks, this paper describes a real time testbed and illustrates some results. In packet switching, video packets can be lost or have random. delay. If a compression code is sensitive to packet loss or random delay, the end-to-end video transmission quality can be unacceptable even at a moderate network utilization. We will demonstrate some real time transmission results over Ethernet. To help developing a good compression code, we need to identify the performance dependence of video transmission on various network transport conditions. To achieve this, a network emulator is used in the testbed. The network emulator can support high speed transmission and can be programmed for different network conditions such as random delay. With the help of the emulator, we can evaluate video quality in real time and develop compression codes for transmission in different networks.","PeriodicalId":203232,"journal":{"name":"Proceeding of 13th IEEE Annual International Phoenix Conference on Computers and Communications","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123971936","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}
