Perepelitsyn A. Methods and tools of multiparametrized PLD-based projects development for embedded systems

The dissertation solves scientific and technical tasks – developing of methods and tools of multiparametrized PLD-based projects prototyping for embedded systems. The goal of the work is to reduce the number of required resources, to increase the productivity or to increase the reliability of FPGA-based embedded systems depending on the provided priority characteristic. In PhD thesis the model of multiparametrized FPGA-based projects is proposed, which takes into account the possibility of changing the bit depth and interpretation of input-output information, functions and architectures of components and projects based on them, which allows to generate many variants for implementation with the required performance and reliability within limited hardware resources of the chip. The method for developing of multiparametrized FPGA-based projects for embedded systems has been improved and now, unlike known ones, provides the ability to choice of architecture and parallel or sequential way of project components implementation, which allows to increase productivity or reduce the amount of hardware resources. The method of reliability improvement of FPGA-based embedded systems has been further developed and now, unlike known ones, provides possibility of various pre developed redundant architectures configuring, which increases the tolerance to SEU and failures. The suggested model, methods and tools have been implemented during development of FPGA based embedded systems in aviation ice-protection system for plane AN-140, medical systems, for RS-codes, cryptographic hash functions and 5 algorithms of block ciphers, including AES, DES and IDEA.
