发明名称 SIMD Compare Instruction Using Permute Logic for Distributed Register Files
摘要 Mechanisms, in a data processing system comprising a single instruction multiple data (SIMD) processor, for performing a data dependency check operation on vector element values of at least two input vector registers are provided. Two calls to a simd-check instruction are performed, one with input vector registers having a first order and one with the input vector registers having a different order. The simd-check instruction performs comparisons to determine if any data dependencies are present. Results of the two calls to the simd-check instruction are obtained and used to determine if any data dependencies are present in the at least two input vector registers. Based on the results, the SIMD processor may perform various operations.
