ARM and PCIe lanes

Since the advent of ARM pc's like the Hp envy x2, i wondered if ARM cpu's could be equipped with PCIe lanes. Then in the future they could have thunderbolt enabled devices (in theory) and faster storage. 

 

Could this be done or would a different system have to be developed to make that happen

I don't see why not, since pcie lanes are handled by the IO section. For example, all the iPhones since the 6s have used PCIe NVMe SSDs.

Make sure to quote me or tag me when responding to me, or I might not know you replied! Examples:

Interested in computer architecture? Still in middle or high school? P.M. me!

 

I love computer hardware and feel free to ask me anything about that (or phones). I especially like SSDs. But please do not ask me anything about Networking, programming, command line stuff, or any relatively hard software stuff. I know next to nothing about that.

We could see the advent of phones with two usb-c ports. This way they phone could be a proper dockable "workstation"(i used the term rarher loosly). One port for charging and one for peripherals. 

 

Personally wouldnt mind not having a headphone jack if there were two usb-c ports

There are all kinds of ARM and MIPS processors which can work with pci-e , either directly in the processor or through a chipset.

AMD even makes an ARM cpu that does supports pci express, Opteron A series : https://en.wikipedia.org/wiki/Opteron#Opteron_A_.2828_nm.29_-_Seattle_ARM_microarchitecture

 

There's nothing specific about pci-e that would make it windows only or x86 only, you just need an operating system Linux , BSD etc and drivers for that device and it will work

Why would you need one port for charging and one for peripherals when one port can do both?

I think you can get both audio and video out of a single USB-C port at the same time.

Can you also charge while listening? That is one of my major complaunst about the lack headphone jack

Didn't you say that you wanted the two USB-C ports for docking?

I did, cause at least there are one poert i can use for charging while listening, but one or both of them could be thunderbolt enabled

He's asking for two so that power and peripherals can be done simutaniously without adapters or special (and thus expensive) cables.

Come Bloody Angel

Break off your chains

And look what I've found in the dirt.

 

Pale battered body

Seems she was struggling

Something is wrong with this world.

 

Fierce Bloody Angel

The blood is on your hands

Why did you come to this world?

 

Everybody turns to dust.

 

Everybody turns to dust.

 

The blood is on your hands.

 

The blood is on your hands!

 

Pyo.

There's nothing really stopping a CPU from interfacing with PCIe, as long as all of the communication protocols line up. As for if it's been done before, yes. NVIDIA has done it with the Tegra K1 at least:

I have a blog! And a list of guides I've posted
