Address generation for high-performance vector processing

A method for accessing a binary data vector in a memory unit comprising a plurality of memory banks in which the binary data vector is stored in portions includes receiving a start address of the binary data vector and a power-of-2-stride elements of the data vector and determining offsets, wherein...

Zusammenfassung:A method for accessing a binary data vector in a memory unit comprising a plurality of memory banks in which the binary data vector is stored in portions includes receiving a start address of the binary data vector and a power-of-2-stride elements of the data vector and determining offsets, wherein the offsets are determined by applying a plurality of bit-level XOR functions to the start address resulting in a Z vector, using the Z vector for accessing a mapping table, and shifting mapping table access results according to a power-of-2-stride of the binary data vector. Additionally, the method includes determining a sequence of portions of the binary data vector in the n memory banks depending on a binary equivalent value of the Z vector, and accessing the binary data vector in the n memory banks of the memory unit in parallel.
