1OpenRISC 1000 CPU architecture support
2======================================
3
4QEMU's TCG emulation includes support for the OpenRISC or1200 implementation of
5the OpenRISC 1000 cpu architecture.
6
7The or1200 cpu also has support for the following instruction subsets:
8
9- ORBIS32 (OpenRISC Basic Instruction Set)
10- ORFPX32 (OpenRISC Floating-Point eXtension)
11
12In addition to the instruction subsets the QEMU TCG emulation also has support
13for most Class II (optional) instructions.
14
15For information on all OpenRISC instructions please refer to the latest
16architecture manual available on the OpenRISC website in the
17`OpenRISC Architecture <https://openrisc.io/architecture>`_ section.
