For those of us thinking they were really ambitious trying to build a 6502 SBC out of little black boxes -- a gentleman by the name of Robert Baruch is building a RISC-V processor out of LSI logic. Yes, a 32-bit processor with 32 registers. He has uploaded a fascinating video https://www.youtube.com/watch?v=yLs_NRwu1Y4 about the first steps, including a (brief) introduction to the RISC-V open ISA CPU, and a discussion about why he chose what chips. It's nice and hardcore, involving things like back-planes and clock signals, resistance values and PCB suppliers. I'm sure some other people here will love it as well.

Oh, and it has blinking lights. Gotta have blinking lights.

For those who haven't heard about RISC-V before, it's a "free and open RISC instruction set architecture", see https://riscv.org/. It's been mostly theoretical so far, but now there is SoC out at https://www.sifive.com/products/hifive1/. Western Digital has announced it will be using, oh, two billion of these things in future hard drives (https://www.anandtech.com/show/12133/western-digital-to-develop-and-use-risc-v-for-controllers) and Nvidia is looking to use the architecture for their microcontrollers on their graphics cards (https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-RISC-V-Next-Gen-Falcon).

Excellent - thanks for the links!

Subscribed, thanks very much!

I watched this a few days ago, and am annoyed that new videos aren't out yet.

The project in blog form: http://www.halfbakedmaker.org/blog/lmarv1-1

I thought the name was familiar. He's also behind Project 54/74 https://project5474.org/index.php?title=Main_Page, reverse engineering TTL chips.

Half-baked is right. He never finishes what he starts. Many cool ideas, all dead on the table.

What's an additional VIA among friends, anyhow?

That seems quite a harshly dismissive comment, Jonathan - not the sort of thing we usually see here. It's worth bearing in mind that anyone with a 6502 interest might visit here. You might be insulting a fellow forum member.

Ed,

Understood. In actuality, I follow Mr. Baruch - both his blog and his YouTube channel. I enjoy his work a lot. And, he happens to be very humble. As such, he tends to be self-effacing (often), and he himself makes a joke out of the fact that he is always working on one million projects and tends to jump around, and start and stop, regularly. Hence the name "Half-Baked Maker." He's a dabbler - and completely self-taught, at that. His posts have a nice "reality" to them. Very down to earth.

Check out his posts about nMigen; they are quite informative.

Regards,

Jon

One thing that can be surprisingly educational, is when someone who doesn't quite understand what they are doing is able to explain their exploration and learning process, including the dead ends.

It’s more of a “jack of all trades, master of none” problem, you know?
