|

								The QEMU emulation of the OpenRISC architecture provides following built in
							 | 
						||
| 
								 | 
							
								features.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								- Shadow GPRs
							 | 
						||
| 
								 | 
							
								- MMU TLB with 128 entries, 1 way
							 | 
						||
| 
								 | 
							
								- Power Management (PM)
							 | 
						||
| 
								 | 
							
								- Programmable Interrupt Controller (PIC)
							 | 
						||
| 
								 | 
							
								- Tick Timer
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								These features are on by default and the presence can be confirmed by checking
							 | 
						||
| 
								 | 
							
								the contents of the Unit Presence Register (``UPR``) and CPU Configuration
							 | 
						||
| 
								 | 
							
								Register (``CPUCFGR``).
