Our architecture is based on the client /server model —clients divide potentially hard problems into sub problems and forward them to different servers in the network. The usage of standardized remote procedure calls (rpc) as the basic mechanism for transmission of data between the workstations allows the extension of the concept for heterogeneous environments.

Hypermedia and temporal –spatial relationships between document media nodes are embedded into the data structure to support flexible presentation of multimedia information. Windows and a specially designed<em>Document Tree Dialog</em>provide an environment for efficient and user-friendly information retrieval. Other system issues such as security and customization are also addressed in the design.

The architecture for the rendering stage, which consists of three independent concurrent units, has been optimised to support the two-layer dynamic load balancing technique. The display stage has also been partitioned to facilitate parallel updating of the pixel data to the dual frame buffers. The design of the frame buffers and the interface logic to access them by direct memory access (DMA) controllers (via three common address and data buses) and the colour video controller are also presented. Simulation results show that the adoption of DMA based memory transfer between the local memory of the transputer nodes and the frame buffers can alleviate the communication bottleneck prevalent in an earlier prototype.","PeriodicalId":100806,"journal":{"name":"Journal of Microcomputer Applications","volume":"73 4 1","pages":"203-213"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84722719","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}
