RiscV open source hardware and Ideas

[Karaya Eins]

Hi

I am designing my own Board, based on beagleboardV

But I want to use RISCV for this

Here are my questions

1. Are their some reference designs available to develop a RISCV motherboard?

2. Are their RISCV chips / cores, that can run ~2 GHz and have ~ 32 GB RAM support?

3. Can you run multiple RISCV chips on the same motherboard, like Intel Xeons running on the same board over intel QPI? 

My purpose is to have 4 boards :

1. 1 for normal low-professional end office and simulation work

2. 1 for numerical heave processing which many, many cores. I know the SIFive freedom core, but one of them doesn't have enough cores.

3. 1 for dedicated multimedia application, image processing, video encoding, etc.

4. 1 for free configuration as time goes on.

I would want mainline linux to run on #1, which #2,3, and 4 should be slaves connected to it over PCI-e or Ethernet over very short distance (e.g. < 5 cm) . The linux running on #1 should be numa aware and seamlessly launch threads in the slave boards if needed.

Is something like that possible? Are their people working on such a thing?

Thank you .
