1 Libre RICS-V M-Class

3 A 100% libre RISC-V + 3D GPU chip for mobile devices
4
5 The Libre RISC-V M-Class is a RISC-V chip that is libre-licensed to the
6 bedrock. It is a low-power, mobile-class, 64-bit Quad-Core SoC at a
7 minimum 800mhz clock rate, suitable for tablet, netbook, and industrial
8 embedded systems. Full source code and files are available not only
9 for the operating system and bootloader, but also for the processor,
10 its peripherals and its 3D GPU and VPU.

12 Onboard the Libre RISC-V M-Class is the
13 [Kazan](https://salsa.debian.org/Kazan-team/kazan) GPU, a
14 libre-licensed software-rendered
15 [Vulkan](https://www.khronos.org/vulkan/) Driver written in
16 Rust that uses LLVM for code generation. Kazan will use Optimised 3D
17 instructions specifically designed and added to the Libre RISC-V M-Class
18 SoC, yet Kazan itself may still be used (unoptimised) on other hardware.

20 The performance target for Kazan on the Libre RISCV SoC is a very modest
21 mobile-class level (1280x720 25fps, 100MPixels/sec, 30MTriangles/sec,
22 5-6GFLOPs), whilst the power budget is very tight: under 2.5 watts in 28nm.
23 With RISC-V being 40% more power efficient than x86 or ARM, this is
24 very reasonably achievable.
