<p><b>Abstract</b>—Using a prime number <it>p</it> of memory banks on a vector processor allows a conflict-free access for any slice of <it>p</it> consecutive elements of a vector stored with a stride not multiple of <it>p</it>. To reject the use of a prime number of memory banks, it is generally advanced that address computation for such a memory system would require systematic Euclidean division by the number <it>p</it>. The Chinese Remainder Theorem allows a simple mapping of data onto the memory banks for which address computation does not require any Euclidean division. However, this requires that the number of words in each memory module <it>m</it> and <it>p</it> be relatively prime. We propose a method based on the Chinese Remainder Theorem for moduli with common factors that does not have such a restriction. The proposed method does not require Euclidean division and also results in an efficient error detection/correction mechanism for address translation.</p>
