It defines a new prototype security architecture based on CHERI (Capability Hardware Enhanced RISC Instructions). image image_alt text /assets/images/content/iStock-1195413927.jpg second test image alt A System on Chip (SoC) implementation of the architecture will provide a DSbD technology platform prototype, enabling industry and academic partners to test real-world use cases and inform future development.	first_column second_column icon title url text /assets/images/content/icon-2.png The Morello code repositories https://git.morello-project.org/ Please refer to the top level [Documentation](https://git.morello-project.org/morello/docs) repository to get started. url icon title text https://developer.arm.com/morello /assets/images/content/icon-1.png Arm's Morello Developer pages Arm's [Developer pages](https://developer.arm.com/morello) provided curated resources for the Morello Program.

Available to download from Arm's [Ecosystem FVP Developer page](https://developer.arm.com/tools-and-software/open-source-software/arm-platforms-software/arm-ecosystem-fvps). FVPs use Arm technology to create a virtual model of the system hardware that can be run as an executable in a development environment. They use binary translation technology to deliver functional simulations of Arm-based systems, including processor, memory, and peripherals. They implement a programmer's view suitable for software development and enable execution of full software stacks, providing a widely available platform ahead of silicon. ### Morello Hardware Development Platform The Morello hardware development platform will become available early in 2022 and will be supported by the same software stack. Note: Availability of hardware will be limited - platforms will be restricted to partners involved in defined research activities. format style text_content text bg-white p-4 my-3 text ## LLVM Compiler with Morello Support Morello is supported by LLVM-based open-source toolchains. Please note, these are experimental toolchains and as such features may be missing. ### Android LLVM/Clang toolchain Includes a C/C++ compiler (clang), linker (lld), debugger (lldb), various utilities (such as assembler & disassembler) and run-time libraries. ### Bare-metal toolchain for architecture exploration projects Includes a C/C++ compiler (clang), linker (lld), a standard C library (newlib), a standard C++ library (libc++, libc++abi) and various utilities (such as assembler & disassembler). [Arm Development Studio Morello Edition](/coming-soon/) is also available as a development environment for the bare-metal configuration. ### AArch64 Linux LLVM/Clang toolchain This toolchain is an experimental AArch64 hosted variant, primarily intended to be used together with Arm's [Morello Instruction Emulator](/coming-soon/). It includes a C/C++ compiler (clang), linker (lld), various utilities and run-time libraries, but does not include a C library. See this [knowledge base article](/coming-soon/) for more details. format style text_content text bg-white p-4 my-3 text ## Firmware The Development Platform is supported by Morello aware ports of standard open source firmware components: [SCP firmware](https://github.com/ARM-software/SCP-firmware), [Trusted Firmware TF-A](https://www.trustedfirmware.org/), [UEFI EDK2](https://github.com/tianocore/edk2) format style text_content text bg-white p-4 my-3 text ## Morello Linux Kernel Modified ACK (Android common Kernel). format style text_content text bg-white p-4 my-3 text ## Nano Android An integrated Android stack supporting a reduced nano profile is hosted in the Morello code repositories. This includes initial modifications to a standard (arm64-v8a) AOSP to support capabilities. Including a modified Bionic library and some pure-capability application ports. format style text_content text bg-white p-4 my-3 text ## CheriBSD The University of Cambridge Computing Laboratory implementation of CheriBSD has also been ported to the Morello Platform. This provides a BSD implementation of a memory safe kernel and examples ports of application frameworks. CheriBSD is maintained and hosted by the University of Cambridge. - [https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/cheri-software.html](https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/cheri-software.html) - [https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/cheri-morello-software.html](https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/cheri-morello-software.html) - [https://github.com/CTSRD-CHERI/cheribsd](https://github.com/CTSRD-CHERI/cheribsd)
