Hi All,

         I want to make use of MMU,TCM & I/D Cache features in ARM.But i got blocked :(  with the following doubts and not able to get clear information from the documents available in net.
 
    -> Is compact OS(like WINCE/Linux) needed to configure MMU in ARM ?
    -> From my application(user mode),can i enter supervisor mode using SWI to configure MMU,       TCM,I/D cache?
    -> In ARM1136J-S,can we use DMA in application, else DMA is used only by the processor to    transfer data from external memory to TCM?
    -> Compared to ARM926EJ-S, in ARM1136J-S is there any improvement in MMU,TCM,I/D Cache  functionalities?

Thanks In Advance :) ,
satish
