Planned hosts


Ask Chewi?




$$$ :(


Looks like "Loongson 3A5000" (4 cores) is the only CPU reasonably available. There is a "3C5000" with 16 cores also but have been unable to find one. Both use a "7A2000" motherboard. There are multiple different listings floating around but this seems like the standard configuration:

There is one 3C5000L for sale (what does the L stand for?) but for $11k:

Ask xen0n

Possible porting hardware


Synposys DesignWare ARC HS Development Kit ($500) -


Xilinx Spartan-7 eval board ($775) - (comes with 4G DDR3L + 1G eth phy + memory controller)

Diligent Genesys 2 ($1000) - - possibly $600 w/ student discount? 1G DDR3

Genesys ZU ($2000) - ?

Comparison of different 7-series FPGAs:


10M50D IP on Intel MAX 10 FPGA (1GB DDR3 I think? does this include a soft memory controller?) ($200) - ,



  1. To be upgraded to 64GB later:
  2. To be upgraded to 4GB later:
  3. Only 16 of 32 total cores in use for now because the kernel hangs during boot if >16 cores are enabled for some reason.
