Designs exist for a 32-bit, 64-bit, and even a 128-bit processor design.</p> <p>You can <a href=https://wiki.qemu.org/Documentation/Platforms/RISCV>emulate RISC-V in qemu</a>, <a href=https://aignacio.com/posts/hdls/mpsoc_riscv/>design your own CPU and synthesize it for an FPGA</a>, or you can purchase a <a href=https://www.sifive.com/boards/hifive-unmatched>commercially built and designed computer with a RISC-V processor</a>.</p> <h2 id=why-not-arm>Why not ARM?</h2> <p>Haiku developers are continuing to work on ARM and ARM64 ports of Haiku, RISC-V just finished first :-)</p> <h2 id=running-nightly-riscv64-images-in-qemu>Running nightly RISCV64 images in qemu</h2> <p><img src=../../../files/screenshots/riscv64-qemu.png alt="RISCV64 in qemu" title="RISCV64 in qemu"></p> <div class="alert alert-info"><p><strong>Beware of bugs</strong><br> There are multiple lingering bugs (<a href=https://dev.haiku-os.org/ticket/17379>#17379</a>, <a href=https://dev.haiku-os.org/ticket/17380>#17380</a>) in RISCV64 Haiku running under QEMU.
