Title:
データプロセッサの結果レジスタの選択したサブワード位置に結果を送る並列サブワード命令
Document Type and Number:
Japanese Patent JP3747936
Kind Code:
B2
Abstract:
In the context of a microprocessor and a program, the invention provides parallel subword compare instructions that store results in a selectable intra-register subword location. In a targeting approach, an instruction permits the location to be specified; alternatively, there can be plural instructions, each associated with one of the locations. In a replicating approach, plural replicas are stored in the alternative locations. In a shifting approach, the instruction moves prior results, so that the number of subsequent iterations of the instruction determines the location of a result. The invention provides for overwriting and content-preserving instructions, and for overlapping and separate locations. The invention allows results from multiple parallel subword compare operations with relatively few instructions. The invention also provides for other parallel subword instructions.
