In this paper, we describe a software mechanism, a software channel, that allows a group of distributed objects to communicate with each other automatically once they are connected to it. Software channels and predesigned distributed objects that are connected to them encapsulate the communication protocol and the network topology to...
Data, buffering is an important mechanism to enhance performance of a database system. In this project, we studied the data buffering mechanism of the Oracle database system and created an Oracle data buffering simulation program in Java. The data obtained from the simulation program w re compared with the performance...
A good code generator must effectively utilize the registers provided by the target architecture. Although a number of register allocation techniques exist, few address the issues involved in multiple register banks and no known techniques exist for effectively using register banks of the same type that are associated with multiple...
Existing graphics systems are too large for students to study in an introductory computer graphics course. We have implemented a lightweight, object-oriented graphics system called OGS for instruction. OGS is written in Java. It demonstrates how a graphics system is implemented from scratch and is intended to help students understand...
Experimental test beds to study Real Time agents are common topic in AI. A principal contribution of this paper is to develop a framework for such experimental test beds. Design and implementation of the test bed and the extension of the framework for different equipment and agents are discussed. Results...
Software development has been characterized by severe schedule slippage, cost overrun and the inability of the developer to estimate with acceptable accuracy the resources and schedule required early in the requirements analysis and functional design phase when critical investment decisions must be made. This estimation difficulty has emerged as one...
We describe a set of data flow techniques and code transformations that translate a single instruction stream, multiple data stream (SIMD) Dataparallel C program into a semantically equivalent single program, multiple data stream (SPMD) C program suitable for execution on shared memory multiprocessor computers, such as the Sequent Balance and...
