According to some embodiments, a conditional Single Instruction, Multiple Data instruction is provided. For example, a first conditional instruction may be received at an n-channel SIMD execution engine. The first conditional instruction may be evaluated based on multiple channels of associated data, and the result of the evaluation may be stored in an n-bit conditional mask register.
