It uses a brand-new multi-heterogeneous unit accelerated computing\n+structure.\n+\n+This chip has 2 RISC-V computing cores and a new-generation KPU (Knowledge\n+Process Unit) smart computing unit.\n+\n+It has multi-precision AI computing ability, works with many common AI computing\n+frameworks, and for some typical networks, its usage rate is over 70%. Besides,\n+the K230 chip supports many peripheral connections and has several special\n+hardware acceleration units (like 2D and 2.5D accelerators). It can speed up\n+different tasks (such as image processing, video processing, audio processing\n+and AI computing). It also has many good features: low delay, high performance,\n+low power use and fast start-up.\n+\n+For more information, see <https://www.kendryte.com/en/proDetail/230>\n+\n+Supported devices\n+-----------------\n+The ``k230`` machine supports the following devices:\n+\n+* 1 c908 cores\n+* Core Local Interruptor (CLINT)\n+* Incoming MSI Controller (IMSIC)\n+* 2 K230 Watchdog Timer\n+* 4 UART\n+\n+Boot options\n+------------\n+The ``k230`` machine can start using the standard ``-bios``\n+functionality for loading the boot image. You need to compile and link\n+the firmware, kernel, and Device Tree (FDT) into a single binary file with\n+K230 SDK(k230_canmv_defconfig), such as ``uboot``.\n+\n+Running\n+-------\n+Below is an example command line for running the ``k230``\n+machine:\n+\n+.. code-block:: bash\n+\n+ $ qemu-system-riscv64 -machine k230 \\\n+ -bios k230_sdk/output/k230_canmv_defconfig/little/uboot/u-boot \\\n+ -nographic\ndiff --git a/docs/system/target-riscv.rst b/docs/system/target-riscv.rst\nindex 3ad5d1ddaf..b0b2f9584f 100644\n--- a/docs/system/target-riscv.rst\n+++ b/docs/system/target-riscv.rst\n@@ -66,6 +66,7 @@ undocumented; you can get a complete list by running\n .. toctree::\n :maxdepth: 1\n \n+ riscv/k230\n riscv/microblaze-v-generic\n riscv/microchip-icicle-kit\n riscv/mips\n", "prefixes": [ "v6", "5/5" ] }
