%0 Journal Article %J IEEE Transactions on Computers %D 2000 %T RT-CRM: Real-Time Channel-Based Reflective Memory %A Shen, C. %A Mizunuma, I. %X In this paper, we propose and present Real-Time Channel-based Reflective Memory (RT-CRM) – a new programming model and middleware communication service for constructing distributed real-time applications on commercially available open systems. RT-CRM provides remote realtime data reflection abstraction using a simple writer-push model. This writer-push approach enables us to easily decouple the QoS characteristics of the writers from that of the readers. This decoupling is crucial in supporting different kinds of remote data transfer and access needs that one often finds in distributed real-time systems. We will describe the design of RT-CRM, along with a set of easy-to-use API to access the RT-CRM service. We have implemented RT-CRM as part of a larger real-time middleware project, MidART.We address many of the important implementation issues including buffer management and QoS support. We demonstrate the feasibility of RT-CRM through a discussion of our application programming support and performance data. %B IEEE Transactions on Computers %V 49 %P 1202-1214 %G eng %N 11
