Abstract

A processor comprising: a register file comprising a group of operand registers for holding data values, each operand register being a fixed number of bits in length for holding a respective data value of that length; and processing logic comprising floating point logic for performing floating point operations on data values in the register file, the floating point logic is configured to process the fixed number of bits in the respective data value according to a floating point format comprising a set of mantissa bits and a set of exponent bits. The processing logic is operable to select between a plurality of different variants of the floating point format, at least some of the variants having a different size sets of mantissa bits and exponent bits relative to one another.
