Method and apparatus for transferring data to or from a memory

摘要

An embodiment of a technique to transfer data includes: operating a memory interface using memory access cycles that each include T successive time slots each provided for transfer of B bits of data, where T and B are positive integers; selecting one of first or second predetermined integers as one of T or B; and transferring a quantity of data Q between the memory interface and another interface. The transferring includes: automatically determining a value of M memory access cycles as a function of the one of T or B; causing a data transfer sequence on the memory interface that includes M successive memory access cycles and thus M·T time slots; automatically determining a subset of the M·T time slots as a function of the one of T or B; and transferring the quantity of data Q through the memory interface during the subset of time slots.
