# Hybrid 3D GPU / CPU / VPU
a stand-alone GPU product (contact us if this is a product that you want).
Our primary goal is to design a **complete** all-in-one processor
(System-on-a-Chip) that happens to include libre-licensed VPU and GPU
-accelerated instructions as part of the actual - main - CPU itself.
+accelerated instructions as part of the actual - main - CPU itself. This greatly simplifies driver development, applications integration and debugging, reducing costs and time to market in the process.
We seek investors, sponsors (whose contributions thanks to NLNet may be
tax-deductible), engineers and potential customers, who are
interested, as a first product, in the creation and use of an entirely
-libre low-power mobile class system-on-a-chip. Comparative benchmark

# Progress:
-* Jul 2020: first ppc64le "hello world" binary executed. 80,000 gate coriolis2 auto-layout completed with 99.95% routing. Wishbone MoU signed making available access to an additional EUR 50,000 donations from NLNet. XDC2020 and OpenPOWER conference submissions entered.
+* Oct 2020 [[180nm_Oct2020/ls180/]] pinouts decided, code-freeze initiated
+ for 180nm test ASIC, GDSII deadline set of Dec 2nd.
+* Sep 2020: [first boot](https://youtu.be/72QmWro9BSE) of Litex BIOS on a Versa ECP5 at 55mhz. DDR3 RAM initialisation successful. 180nm ASIC pinouts started [[180nm_Oct2020/ls180]]
