An apparatus, system, and method for providing a multi-dimensional data structure and address generation unit configured to calculate real addresses in order to access the multi-dimensional data structure in a desired pattern. The address generation unit may be configured to calculate the real addresses by executing a series of nested loops pre-programmed into the address generation unit prior to accessing the multi-dimensional data structure. The address generation unit may receive as inputs a set of parameters defining characteristics of the nested loops such as a starting offset, number of iterations or step size for loops, data structure dimensions, or loop starting point inheritance. A vector processor may then access the multi-dimensional data structure at the real addresses calculated by the address generation unit. The multi-dimensional data structure may be stored in a buffer in a data memory.
