OpenRISC Basic Instruction Set (ORBIS32/64) with 32 bits wide instructions aligned on 32-bit boundaries in memory and operating on 32 bits and 64 bits data There are many implementations for OpenRISC like or1200 and mor1kx. refer to the`OpenRISC 1000 architecture manual openrisc.github.io/or1k.html. Build instructions for OpenRISC toolchain and Linux¶. In order to build and run Linux for OpenRISC, you'll need at least a basic toolchain and, perhaps, the The OpenRISC instruction set architecture (ISA) is a simple RISC Uniform-length instructions (32-bit instructions aligned at 32-bit boundaries).

From a debugging perspective, there are three data areas that are manipulated by the The OpenRISC 1200 (OR1200) is an implementation of the open source OpenRISC 1000 RISC pipeline and is capable of single cycle execution on most instructions.
