RISC-V

Everyone is just building CPU cores, but for a complete system we also need a memory controller, UART, PCIe, USB - is anyone working on that?

opencores.org doesn't seem to have anything in a working state yet.

don't they?

isn't RISC-V aiming for SoC?

The largest chip I found there has 256kB of Memory and no way to control external memory

Impressive nonetheless, but it's a research project far from being able to run a general purpose OS

What's the story behind that chip layout?

DDR3 is pretty hard apparently, but rather unsexy.

There is however a working DDR1 controller that came out of the Milkymist project

What the fuck, why? No company will invest enough into R&D to make a ASIC complex enough to run Linux, and the NRE costs will make it impossible for open source projects.

guess that's their thing

I imagine Google or Facebook could pull that off.

FPGAs are better.

You'd still need a UART, some RAM, a USB controller, and a NIC of some sort.

you can do it

>>61994430
PCIe controller would be a good start, so you can plug in existing cards

>>61992079
Never. Hardware cucks didn't care about freedom?

What is cyclone v then?

>>61998999
an FPGA

It will never run a general purpose OS since they don't plan on implementing virtual memory support. I asked them.
