INSTRUCTION FOR ELEMENT OFFSET CALCULATION IN A MULTI-DIMENSIONAL ARRAY

摘要

An apparatus is described having functional unit logic circuitry. The functional unit logic circuitry has a first register to store a first input vector operand having an element for each dimension of a multi-dimensional data structure. Each element of the first vector operand specifying the size of its respective dimension. The functional unit has a second register to store a second input vector operand specifying coordinates of a particular segment of the multi-dimensional structure. The functional unit also has logic circuitry to calculate an address offset for the particular segment relative to an address of an origin segment of the multi-dimensional structure.
