In this paper we present an efficient data fetch circuitry to retrieve several operands from a n -way parallel memory system in a single machine cycle. The proposed address generation unit operates with an improved version of the low-order parallel memory access approach. Our design supports data structures of arbitrary lengths and different odd strides. The experimental results show that our address generation unit is capable of generating eight 32 − bit addresses every 6 ns for different strides when implemented on a VIRTEX-II PRO xc2vp30-7ff1696 FPGA device using only trivial hardware resources.
