The present invention provides a collision avoidance manager for use with single-port memories. In one embodiment, the collision avoidance manager includes a memory structuring unit configured to provide a memory arrangement of the single-port memories having upper and lower memory banks arranged into half-memory portions. Additionally, the collision avoidance manager also includes a write memory alignment unit coupled to the memory structuring unit and configured to provide double-data writing to the memory arrangement based on memory collision avoidance. In a preferred embodiment, the collision avoidance manager also includes a read memory alignment unit coupled to the memory structuring unit and configured to provide double-data reading from the memory arrangement while maintaining the memory collision avoidance.
