    Emulator of EPOS-73

    The behavioral model of the old Soviet calculator EPOS-73

    This project introduces a console application designed for functional and behavioral emulation of the old Soviet calculator EPOS-73 (ЭПОС-73) also known as Elektronika B3-11 (Электроника Б3-11). The project is conceived as an auxiliary for verification of the switch-level simulator based on Verilog HDL of the said apparatus. Calculator model EPOS-73 is interesting in that it was one of the first models of Soviet computing performed at LSI, that were fully designed by Soviet engineers. It was...

    Primes

    Calculate primes by using extremely fast sorting

    This project considers the problem of calculating primes as a sorting problem. It includes the most efficient tree-based sorting algorithm that is possible and shows that finding a new prime can be done by sorting the differences between the previous primes in the right way. Unfortunately it has turned out that going this way is even more slowly than trying to find primes by brute force. So it can only be used as a test with heavy load for the sorting algorithm, which can be used for...
