1. An algorithmic method to perform branchless constant-time ASCII string integer to decimal binary format conversion on vector processors, said ASCII string integer comprising a sign, one or digits, and a string terminator and said method comprising: execution of the conversion, using code comprising a fixed sequence of a constant number of instructions; parallel detection of the string's terminator and masking of all unused characters; parallel conversion of all characters of the string into corresponding decimal binary values; parallel multiplication of each of the decimal binary values with a power of 10 corresponding to where the decimal binary values are placed relative to each other; and aggregation of results of the parallel multiplication into a final signed decimal binary result.
