  13
  14 With LibreSOC, you can take complex algorithms usually intended for
  15 power hungry servers with big fat GPUs, and run them on tiny devices
  16 like smartwatches, cellphones, and pocket drones without changing your
  17 code at all.

  21 <h2 class="display-5">Hasn't Somebody Already Done This?</h2>
  22
  23 To the best of our knowledge, no. The closest systems would be ARM Cortex
  24 devices which currently offer mediocre GPU and OpenCL support. Often
  25 times, it is quite diffcult for customers to get their hands on the
  26 drivers and install them due to their locked down nature. LibreSOC is
  27 providing our own Free/Libre drivers. Easy as 1, 2, 3!

  49 # Our Team
  50
  51 We are proud of our talented and diverse [team](about_us).
  52
  53 # Our sponsors
  54
  55 * [Purism](http://puri.sm) donates to us through [NLNet](nlnet)
  56   charitable gifting
  57 * [Raptor CS](http://raptorcs.com) has given us access to a powerful
  58   18-core 128 GB RAM TALOS II workstation, online.

  60 # How Can I Help?
  61
  62 If you would like to fund us, see [[funding]]. We currently have some
  63 funding and always appreciate more!  If you are a Corporation or an
  64 individual you can donate tax-free to NLNet, and they can in turn gift
  65 our developers.  Contact lkcl@lkcl.net for more information.
  66
  67 If you want to write code with us (and receive donations from NLNet
  68 for doing so), keep reading.  If you want to *learn*
  69 so that you can write code with us, see below.  If there is anything else,
  70 just get in touch on the list, there is plenty to do.
  71
  72 1. First, join the
  73 [mailing list](http://lists.libre-riscv.org/mailman/listinfo/libre-riscv-dev),
  74 introduce yourself (people will happily say "hello" back"). Read through
  75 [recent posts](http://lists.libre-riscv.org/pipermail/libre-riscv-dev/)
  76 and the [[charter]], and let everyone know, on the list that you're
  77 happy with it and agree to it.
  78 2. The next thing you should do is read through the [bugs
  79 list](http://bugs.libre-riscv.org) and see if there are any bugs that
  80 pique your interest.
  81 3. After that, go ahead and take a look at the
  82    [git repositories](https://git.libre-riscv.org).
  83 Try and clone a repository with
  84 ``git clone https://git.libre-riscv.org/git/repositoryname.git``
  85 4. If you plan to do HDL work, you should familiarize yourself with our
  86    [[HDL_workflow]].
  87 5. We do have funding available (see [[nlnet]]) upon completion of issues -
  88 we are also working on procuring more funding which gets the project to
  89 nanometre scale tapeout.
  90 6. After all this, if you feel that Libre-SOC is a something
  91    that you would like to contribute to, add yourself to the
  92    [current_members](about_us) page, fill in some information about yourself,
  93    and join the mailing list and say hello.
  94
  95 Also note that you can edit this wiki.  You can experiment in the [[Sandbox]].
  96
  97 ## How can I learn?
  98
  99 The whole purpose of this project is to be a learning environment as well
 100 as an actual business.  If you want to learn how to do ASIC design, with
 101 a view to contributing or starting your own ASIC business, start here:
 102 [[3d_gpu/tutorial]]. Yes, really: do not let anyone tell you that you
 103 can't learn this stuff too.
 104
 105 Along the way, if you find any [[resources]] or links that you found
 106 particularly helpful, please add them to that page so that other people
 107 can also benefit (and you have a place to remember them, too).
 108
 109 ## Needed Skills
 110
 111 Most labor is currently being applied to developing the GPU portion of
 112 the Libre-SOC.
 113
 114 The highest priority needed at the moment is a c++ engineer to work on
 115 a MESA 3D driver. This will begin life similar to SwiftShader however
 116 retaining the vectorisation and predication intrinsics as well as hardware
 117 accelerated opcodes (all of which SwiftShader lacks)
 118
 119 Medium to long-term we need HDL engineers. Particularly those familiar
 120 with nMigen or just python.  Most of the techniques being used require
 121 software engineering skills (OO design, polymorphism) than they do more
 122 traditional HDL programming skills. Basically if you have experience in 2
 123 of the following you'll do fine: python, nmigen, verilog/VHDL/gate-level
 124 design. See [[HDL_workflow]]
 125
 126 Also, individuals with experience in formal mathematical verification
 127 are quite welcome.
