Abstract

The article considers the possibility of implementing an associative coprocessor block on a modern element base for specialized computer systems. The goal of the article is the development and study of the associative co-processor block on PLD, for specialized computing, for example, multi-processor, systems, performing associative function and data storage functions. The object of research and development of this article is the associative coprocessor based on PLD. The search operation is widely used in different purposes as users and systems. However, this operation is one of the most labor-intensive and requires time-consuming when implemented in the traditional way, when the search data is sequentially read from the machine RAM to the CPU, where they perform the appropriate operation. The paper proposes associative co-processor connected to the PCI bus of a computer system, providing search and comparison of “more – less” simultaneously in 32 of said pre-loaded in the associative memory. Finally, conclusions have been made. The use of the VHDL language as a universal means of hardware description of integrated circuits provides the flexibility of the project and the ease of debugging the operation of the device. Modeling the associative co-processor was carried out in CAD Web pack ISE of Xilinx company. This allows to evaluate the correct operation of the hardware coprocessor in the composition of computing systems without building the actual layout. Introduction efficiency of the module is assured by the fact that the coprocessor performs a time-consuming operation to search for and compare data and thus relieves the CPU and increases the performance of the computing system as a whole. The results obtained in the article can find application in the search engines for different purposes: servers, databases, search machines used at stations, airports and for fast implementation of the search task operating systems.
