ABSTRACT:
A mechanism for performing fast and efficient full shift, merge, insert and bit alignment functions within one operating machine cycle of a host primitive instructions set computing system. In general, the circuitry performs a ring shift under control of a mask. The circuitry further combines essentially parallel rotate and mask and merge functions all executable in one machine cycle. The circuitry further allows the provision of powerful bit, digit, and bit rotate with mask instructions which are particularly useful primitive operations for decimal packing and unpacking functions as well as for implementing floating point preshifting and normalization functions.
