1. A method of memory compression in an embedded system with an operating system supporting memory management, the method comprising the steps of:

  • receiving a request from the operating system to swap a page of data to a swap area;

    compressing the data into a compressed page of data; and

    allocating space in a compressed area of memory to which the compressed page of data is swapped where, if the compressed data does not fit within the compressed area of memory, additional memory is requested from the operating system to enlarge the compressed area of memory.
