EMULATING AGENT AND METHOD FOR REFORMATTING COMPUTER INSTRUCTIONS INTO A STANDARD UNIFORM FORMAT

An emulating agent and method is provided that receives numbers having si, exponents and significands of varying lengths and possibly configured in a variety of incompatible formats and to reformat the numbers into a standard uniform format for uniform arithmetic computations in processors operating with different architectures. In one embodiment, the emulating agent has a three-field superset register configured to receive the sign of a number in a first field, the exponent of a number in a second field and the significand of a number in a third field, regardless of the original format of the number, resulting in a number represented in a standard uniform format for computation. The embodiment also allows high level access to the fields to allow users to control the size of the numbers inserted into the fields.
