Systems and methods for performing single instruction multiple data (SIMD) operations on a data set. The methods may include examining a structure of the data set to determine what reorganization may be necessary to facilitate SIMD processing. The method may include selecting a stored bit mask corresponding to the organization of the data set and loading the bit mask into an application specific register (ASR). Subsequently, the data may be reorganized inline according to the ASR as the data is loaded into the SIMD functional unit such that the SIMD functional unit may operate on the data set. The results of the SIMD operation may be written to a results register.
