ICEpi Zero ECP5 v1.2 is now officially supported. The SDRAM controller has been reworked to meet JEDEC specs with a refresh scheduler and open row policy for fewer cycles. FPGA RISC-V @icyelectronics

@icyelectronics Icepi Zero looks like a splendid piece of hardware I was waiting for, ECP5 with all the connectors I need and RAM! Judging by the speed KianRV SoC is running, it will be a complete overkill for my retro stuff ;) I immediately ordered 2 from @crowd_supply @icyelectronics

New favorite FPGA board: Tiny, running Kianv Linux. This week I’ll solder it for network support, and maybe finally implement cross clock domains too.

Had to rework the SDRAM controller, it was acting up with Winbond. Now it runs with Micron and Winbond… plus added a refresh scheduler. Hitting the repo soon… and 3 weeks vacation – lmao. @micko_mame @YosysHQ GateMate should work with the new controller.

@icyelectronics this setup is sweet, love seeing linux run on these boards, perfect for diy projects

Allow me to introduce my RISC-V #KianV machine, which boots #Linux on the FPGA with SDRAM. It's a simple design, but powerful. Starting with my vacation. How awesome... Linux and RISC-V forever... #Verilog is my life. #riscv

I can't believe I dared to do it: an iCE40HX8K FPGA that boots a mainline 6.13.0-rc1 #Linux kernel via OpenSBI, running 100% KianV SV32 (MMU) RV32IMA Zicntr Zicsr Zifencei SSTC RISC-V. Incredible... amazing board, thanks to Machdyne UG's Kuchen iCE40HX8K FPGA board. #ice40 RISC-V International YosysHQ

It’s still crazy that an iCE40HX8K FPGA runs the Linux 6.15-rc1 mainline kernel with networking. It’s crazy. KianV RISC-V has lost its innocence.

Forget GPUs. Map the RISC-V register file to HDMI, use it as a framebuffer, and blast RISC-V across the screen on a kianV bare-metal beast. Dave W Plummer

Let's write C++23 code in an academic style. I aim to implement a modern C++ threading example using 100 threads—both with and without mutex protection—on my self-designed, from-scratch RISC-V Linux SoC, KianV

Wrote a brutal C++23 CPU monitor for my KianV RISC-V Linux SoC on FPGA. It uses 8 GPIO LEDs to show live CPU load. Clean modern C++, signal-safe shutdown, no mercy , just pure hardware feedback.

Yo, testing KianV StealthV on the Genesis 2 now with 1 GB of RAM and 100 MHz. This feels fucking awesome. DDR RAM is pure porn. Custom RISC-V Linux running on my own five-stage pipeline CPU. What more could you want? Of course, a badass out-of-order core is coming later. It's still in the design phase, though.

KianV Stealth Linux RISC-V SoC. First bring-up with a 5-stage pipeline CPU and GShare branch prediction. Running at 25 MHz for now during bring-up, but already timing clean at 50 MHz. Ported my old SoC parts like SDRAM controller and UART to the new pipeline core. Caches are still primitive, memory is single-beat and one clock domain only. Tons of potential left. Fun summer ahead.

fixes a gap in crypto privacy. Traditional privacy coins like Monero and Zcash protect transactions, but not computation. App logic, user data, and state transitions are still exposed. Our RISC V privacy runtime brings deterministic execution, zkSNARK proofs, and fast cryptographic precompiles into one framework, letting anyone build private AI, private DeFi, private data collaboration, and private bridges/apps. Privacy moves from value to computation. Now available on the open-source privacy platform (OSPP). Enjoy this fun demo we built. Feel free to replicate the steps and try our RISC V privacy runtime yourself~!

“A cutting edge blueprint for the future of semiconductor chip design, called ‘RISC-V’… got it’s start right here on the campus of UC Berkeley. The same Berkeley professor who helped create the technology, is now partnering with Tsinghua University in China… The problem is that the TBSI partnership has a record of collaboration with Chinese military-linked universities. We must make sure that advanced technologies, such as RISC-V, developed through federal funding support are not being transferred to China by way of under-regulated collaborations between U.S. and Chinese universities at the cost of America’s national security.” - Chairman
