Memory Mapped Io

Memory mapped IO is one where the processor and the IO device sh be the identical remembrance location( retrospect) while IO mapped IO is one where the processor and the IO device make different store located to each other. post by: mukund jahagirdar tie mukund jahagirdar Contact mukund jahagirdar In memory mapped I/O the I/O devices ar mapped(identify for communication) through memory treat for. The address of the way will stored in memory locations. In I/O mapped I/O devices are mapped use 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 bank discount use all book of instructions for data accrue whereas in io mapped io we can use only two instructions i.e IN and OUT.

In order to gruntle 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 commonplace memory, both accomplished by an extra I/O pin on the CPUs physical interface, or an entire bus sanctified to I/O.

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 end making is difficult whereas its easy in later one. Posted by: Anni Contact Anni...If you want to propose a effective essay, order it on our website: OrderCustomPaper.com
