Today I finally got graywolf and qflow running.
It’s available for download as a package from my OBS build repository:
https://build.opensuse.org/project/show/home:leviathanch:asic
The first glimpse of the transistormask of the RISC-V we’re going to tape our is here:
I’m using cliffords picorv32 which can be cloned from github:

Dragoncore/Loongson/龙芯 (step one)
Hi folks
I’m now living in China.
Here are some pictures of my first run of the 龙芯芯片.
Although the lab is still a total mess/battle zone is started working on the FOSS tablet project already.
As you can see the board I got from 龙芯 does power up and loads the PROM.
Next step is to compile a vmlinux for 2H in order to test the system.
“Money printer”
Hi
I’m working on a python script which uses a cascaded triangular arbitrash in order to multiply money.
But so far the calculations seem to be all unsatisfying.
What I’m doing so far is fetching and filtering and interpolating the values in order to estimate the trade development:

Two grakas, three displays… and X.org >.<'
Hi folks
This one looks easy… X.org should just detect it, right?
dizzy-6:/home/leviathan # lspci | grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation GT200b [GeForce GTX 275] (rev a1) 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450]
Well… It didn’t. It had to tinker a whole day until I got the right xorg.conf
I figured I share it with you:

Using gamma ray as energy source?
A friend asked me a question on how feasible it would be to use gamma rays as an energy source. So let’s crunch some numbers: The wavelength of gamma rays is
\[\lambda=\frac{c}{f}=0.005 nm\]
Since the optimum length l for an antenna is
\[l=\frac{\lambda}{4}=0.00125 nm=1.25 pm\]
We are a bit in trouble here since the radius of the atom Sodium for instance is approximately 160 pm.
Physically it’s just not possible to build such a small antenna.
My trip to China (Chapter 4)
Today… Let’s just say: I’ve found the StarBucks.
It’s exactly as the StarBucks in Switzerland. I mean exactly the same.
Only that an Americano middle sized cup (for take away) is only 3.50 CHFr and not 5.00 CHFr.! ^_^
Agricultural paradise
Well… I didn’t find it in time… Also as far as I could see… It’s not really as interesting as some travelling blogs have described it.
Lovers road
Well. I didn’t go straight there either because I was stuck at the bubble tea and steamed bread corner where I’ve found fresh Manju (with red bean stuffing! *_*) as you can find a recipe for on my blog.
Also I’ve found Banh Bao… After this dinner I was so stuffed that I decided to roll back home.
Ahh! I talked Chinese a lot more today ^_^

Botanic “garden”
If you expect something like the botanic garden in Zürich or elsewhere. Don’t bother. It’s not… Here some proof.
My trip to China (Chapter 2)
Park in Zhuhai (珠海)
Actually just one of so many parks in 珠海. I passed by this place on my way to the 客车68号 (Bus number 68) to the office of Allwinner Technology.
My way to Allwinner Technology
Since the security guard at the entrance already looked a bit confused when I sat down and tried to make clear to him with my dictionary that I was two hours too early for the meeting I’ve let it be to make pictures of the entrance.
Just be told, that the company has a beautiful modern new building now with leather seats and mings vases and two big red Chinese lanterns at the entrance.
A beautiful office building! *_*
Dinner (sponsored by Allwinner)
Best food of my life (2.0)! ^^
我不想回来瑞士! (I don’t wanna go back to Switzerland) *_*
Ah and btw, maybe I don’t have to.
I seems as if the dinner has brought up some additional business ideas which would justify my employment at their company =D
