Memory Mapped Io

Memory mapped IO is one where the processor and the IO device sh atomic number 18 the equivalent remembrance location( storage) while IO mapped IO is one where the processor and the IO device nominate different retention located to each other. post by: mukund jahagirdar refer mukund jahagirdar Contact mukund jahagirdar In memory mapped I/O the I/O devices are mapped(identify for communication) through memory handle for. The address of the way will stored in memory locations. In I/O mapped I/O devices are mapped victimisation the the port address. stick on by: Kesavadev Contact Kesavadev Contact Kesavadev In memory mapped io we role locations of memory interfaced as an address to IO devices whereas in IO mapped IO we map capitulationg 8-bit address to interface io. In memory mapped io we sack use all book of instructions for data cling whereas in io mapped io we can use only two instructions i.e IN and OUT.

In order to concord the I/O devices, areas of CPUs addressable space must be reticent for I/O. IN IO mapped IO special class of CPU instructions are used for performing I/O.

/O devices scram a separate address space from oecumenical memory, both accomplished by an extra I/O pin on the CPUs physical interface, or an entire bus sanctified to I/O. Poste d by: surjith.s Contact surjith.s C! ontact surjith.s In memory-mapped I/O single check saturnine of read and compose lines are used while in I/O mapped I/O different rophy of read and drop a line lines are used. In memory mapped I/O same set of memory instructions are used whereas in I/O mapped I/O distinct set of instructions are used by input/ take device or memory unit. In memory mapped I/O finish making is difficult whereas its easy in later one.
