1. A control system comprising:

  • a receiving device configured to receive externally provided data;

    a host processor for processing the data;

    a system memory including a buffer memory area for storing the data wherein the data in said buffer memory area is non-fractured and stored in substantially contiguous memory locations; and

    a DMA controller in operational connection with the receiving device, the host processor, and the system memory, the DMA controller providing buffer management control for controlling the storage of the data in the buffer memory area wherein said buffer management control further comprises dynamically fracturing the buffer memory area, whereby the dynamic fracturing forms substantially contiguous smaller memory fragments from said buffer memory area.
