minsoc is a minimal OpenRISC-based system-on-chip, that is easy to configure and implement, but still uses the OR1200 processor implementation. OpTiMSoC is a flexible multicore system-on-chip that is based on a network-on-chip and connects a configurable number of OpenRISC (mor1kx) processors to arbitrarily large platforms.

The OpenRISC 1000 architecture allows for a spectrum of chip and system implementations at a variety of price/performance points for a range of applications. It is a 32/64-bit load and store RISC architecture designed with emphasis on performance, simplicity, low power requirements, and scalability. OpenRISC 1000 targets medium and high ...

OpenRISC Floating-Point eXtension (ORFPX32/64) with 32-bit wide instructions aligned on 32-bit boundaries in memory and operating on 32-bit and 64-bit data. Reserved opcodes for custom instructions. Note: Instructions are divided into instruction classes. Only the basic classes are required to be implemented in an OpenRISC 1000 implementation.

The marocchino OpenRISC implementation also has the advanced features of the mor1kx. The marocchino then expands on this with more advanced features: A 64-bit FPU implementing OpenRISC’s ORFPX64A32 extension. It implements an Out-of-order pipeline which helps to avoid pipeline stall’s providing higher execution performance.

For building your own software, OpenRISC is supported by a 32-bit GNU toolchain offering C and C++ support. The toolchain is available in several forms, depending on your use case: or1k-elf for bare metal use, based on the newlib library. or1k-linux-uclibc for Linux application use, based on the uClibc-ng library.

Ubuntu OpenRISC VirtualBox image. The purpose with the Ubuntu OpenRISC VirtualBox image is to make it SUPER easy to get started with the OpenRISC processor platform, both with hardware and software. The VirtualBox image contain the necessary tools pre-installed for both hardware and software.

The OpenRISC repositories differ from the upstream repositories in that there might be changes in the upstream code that have not yet been merged. Also, there may be architecture specific code that is not yet in the upstream distribution. Of course you may desire to check out a repository for a certain release by checkout of the respective git tag.

May 28, 2021 · Mainline OpenRISC support will be available in the upcoming 9.0.0 release of GCC. Note, this has been a clean room rewrite of the OpenRISC gcc port. The old port can still be found in..... more; 16 Mar 2018 » GDB Upstreaming and Binaries: 7.2.0 (Stafford Horne) We are proud to announce that the OpenRISC port for gdb has been merged upstream ...

Feb 18, 2017 · We have released an updated version of the gcc 5.4.0 toolchain with x86_64 binaries for easy consumption. The new version, tagged or1k-5.4.0-20170218 is available on our github release page.. There are 3 different binaries to choose from: newlib - this is the baremetal toolchain good for running c code directly on the openrisc cpu without an operating system
