Abstract
Partitioned sigma instructions are provided in which processor capacity is effectively distributed among multiple sigma operations which are executed concurrently. Special registers are included for aligning data on memory word boundaries to reduce packing overhead in providing long data words for multimedia instructions which implement shifting data sequences over multiple iterations. Extended partitioned arithmetic instructions are provided to improve precision and avoid accumulated carry over errors. Partitioned formatting instructions, including partitioned interleave, partitioned compress, and partitioned interleave and compress pack subwords in an effective order for other partitioned operations.
