ABSTRACT:
A data processor for latching in a floating point register floating point data having exponent parts of fixed and variable lengths, which are transferred from a main storage or an arithmetic unit as they are, but are not converted to another data expression type. When the data of the two representation types are to be input for computations from the floating point register or storage to the arithmetic unit, there is provided circuitry for controlling the data to be computed after that data has been converted into data having an exponent part of fixed length representation, in the arithmetic case of data having an exponent part of the variable length representation, and data to be computed without any data conversion in the arithmetic case of data having an exponent part of the fixed length representation. By thus controlling the two computations discriminatively, it is possible to realize the processing time periods matching the respective data widths.
