ABSTRACT:
A high speed system utilizing programmably controlled ranks of multiplexers for reformatting data from programmably selected first formats to second formats is described. Interleaved input data is utilized to optimize reformatting rates. The reformatting system provides field selection and justification together with the capability of complementing and magnitude generation of the selected fields. Floating-point operands in two different floating-point formats can be unpacked, that is the characteristic separated from the mantissa and properly aligned, and can be packed by positioning and recombining the characteristic with that associated mantissa. Throughout the entire reformatting process, parity for selected bit groupings is maintained, thereby allowing through checking of reformatting operations. The reformatting system includes programmably selectable constant generation.
