So what is your input and output, so communication with peripherals or devices is usually referred
to as input and output.
We call them as I abbreviated as Al.
So there are two techniques by which the two two methods of performing and or input output between KPO
and the peripheral devices, first one is memory mapped and the second one is Porthmadog in memory mapped
and will be using the same Atrous bus outerspace to address both memory and your devices.
An interest is accessed by the CPA, it can either refer to an ocean of memory, just physical rent,
or it can refer to a memory of the Iot in case of memory map that you as.
And the inspections to access the memory seen for accessing the in case of memory, or you will have
the same instructions to access the memory as well as to access the devices, for example, of the example
of but also to use this memory map that you use.
Adding The second one is I'll map out your passport map.
We call it as isolated you.
So here we have different precipices.
Yeah, we have SeaMicro spaces in memory map, but in case of a map, you'll we have different atmospheres
for memory and utilizers.
So how is this achieved?
The process may have an extra eye open on the CPU physical interface or it may have an entirely separate
bus which is dedicated for you.
And in case of the money that we have seen, CPR instructions to access memory as well as devices,
but in case of your mouth, are you all over the map, be use separate instructions, software, CPU
instructions to access your devices.
So that's an example of processors which uses AMAP internal processes nowadays, 686 to support both
human value and memory you.
So this is the space in case of Portmeirion, you have a separate space for memory and then you have
a separate space, but accessing the memory of the devices, whereas in case of memory, my Matteo,
there is a single space and you have a space shared between memory and Iot this.
