    hi
    i have a basic doubt
    does all controllers support paging
    wat are the essential hardware requirement for paging

    What memory are you talking about ?

    internal eeprom, program memory, ram, external memory ?

    I don´t see any problem paging memory, but you need to have some reason to do it. For example if the micro has small internal ram but large external, then paging makes sense for loading some chunks of the extrnal memory ínto the internal. You don´t need any hardware for this, but you need to cope with the overhead that paging creates, like translating the addresses and transferring the pages.

    hi thank you for u r reply
    actualy i was doing can calibration protocol implementation on a renesas R32C153 microcontroller
    the protocol specification specifies some page switching command
    my controller has following specification
    1.4GB ADDRESS SPACE
    2.48-Kbyte internal RAM
    3.1-Mbyte internal FLASH ROM
    4.8KB E2dataFlash
    AND THE CONTROLLER WHICH EVER I WORKED B4 HAS SEPARATE MMU or data page pointer ....in this controller I DINT FIND ANYTHING LIKE DAT
