ABSTRACT:
A data processing apparatus compares first and second floating point operands to produce a comparison result. For each floating point operand, a first component is derived from a predetermined number of MSBs of the fraction component which is less than the total number of bits constituting the fraction component. The sign and exponent components of the first and second floating point operands are compared to produce a plurality of signals. If possible, the comparison result is determined from the plurality of signals. For each floating point operand, a second component is derived from the bits of the fraction component of that floating point operand other than the predetermined number of MSBs. The second components of the first and second floating point operands to are compared produce a further signal. The comparison result is determined from the plurality of signals and the further signal.
