1. An algorithmic method to perform branchless constant-time conversion of an ASCII string real number, said real number comprising a sign byte, an integer part, a fractional part, a decimal point separating the integer part from the fractional part, and a string terminator, to a binary decimal floating point real number representation on a vector processor, said method comprising, implementation of code comprising a fixed sequence of a constant number of instructions to execute one or more steps of the conversion, said conversion further comprising, detection of the sign byte and assignment of a unique binary value to said sign byte depending on the sign being positive or negative; parallel detection of the string terminator and masking of all unused characters; parallel detection of the decimal point that separates the integer part of the real number from the fractional part of the real number; parallel conversion of all characters of the string into corresponding binary decimal values; parallel multiplication of each of the binary decimal values with a power of ten corresponding to the placement of each of the binary decimal values inside the decimal number to obtain individual binary results; aggregation of the individual binary results of the parallel multiplication into a first intermediate binary result; multiplication of the first intermediate binary result with a floating point power of ten corresponding to a placement of the decimal point to obtain a second intermediate binary result; and multiplication of the second intermediate binary result with the binary value assigned to the sign to get a final floating point binary decimal result.
