Interleaved memory schemes have been used to increase the memory bandwidth. In this paper, we propose a new interleaved memory scheme called PSIM (Periodically Shifted Interleaved Memory), which allows high memory bandwidths at the sacrifice of very small memory space. It is a stride dependent scheme where the processor utilization is 100% for most strides using a power-of-two number of memory modules. We show, analytically and then by simulation, that the efficiency of PSIM is consistently higher than not only earlier stride dependent schemes but also stride independent schemes for both short and long vector accesses.
