Multiprocessor systems are possible to use for parallel computation related to association and classification tasks. For efficient solution above described tasks are used neural networks in which computation is processed in sense of data-driven executing. Similar model is used in data flow computers also. This article describes abilities of transformation(More)
This paper deals with recent results of a supporting mechanism for efficient evaluation of network traffic parameters. Most of the network monitoring tools store the measured data in a database for the later analysis. With the growth of the data in the database, processing of queries is becoming more and more time consuming. This fact results in an(More)
Dynamic data flow system is a group of interconnected data flow driven processor elements, solving one compound task. Data flow systems are systems driven by flow of data, effectively using natural parallelism rising during processing of large amount of data, for example: image processing, sound processing etc. Speed of dynamic data flow system depends on(More)
This paper deals with the solution of database related problems which can occur during network traffic monitoring. During data evaluation through a database excessive response time can be noticed. While the time necessary to obtain the data from the database has a significant effect on the result of the monitoring, it is important to keep its value as low(More)
The article introduces proposed computer architecture with data driven computation model based on principles of tile computing as the modern approach to multi-core design of microprocessors. Special attention is paid to the description of characteristics of architecture, which are priority of instructions execution with coloring of instruction priorities,(More)
The data flow model of execution offers attractive properties for parallel processing. First, it is asynchronous: Because the readiness of data dictates the instruction execution. Second, it is self-scheduling: The data flow graph representation of a program eliminates the need to explicitly manage parallel execution. The architecture described in this(More)
The article presents a security solution of mapping RBAC model in to Linux kernel systems. RBAC management model represents an effective concept of mapping user organization structure to access control of computer systems objects. Definition of RBAC model roles allows declaring permitted operations with specified security policy. Based on the roles, system(More)
Photorealistic rendering is very often used area in computer graphics. It is used to display human body in medicine, buildings in architecture and also in other areas of our life. For photorealistic rendering are very important powerful computer, than it is relative difficult on computing. To render a 3D object in computer graphics a high efficient computer(More)
