It may also loonhson the data directly from one of the result buses if its source register number matches the destination register number of the result bus. Archived from the original on 21 June Early implementations of the family lacked four instructions patented by MIPS Technologies to avoid legal issues.

Most common open-source applications including OpenOffice. Retrieved 26 May From Wikipedia, the free encyclopedia. The value is then sent to memory access queue, where dynamic memory disambiguation and memory forwarding is performed. Views Read Edit View history. It was formerly called Godson. The issued instruction reads its source operands from the physical register file and is sent to the associated functional loongxon. Archived from the original on 17 April A new physical register is allocated for ,oongson logical destination register, and the logical source register is renamed according to the latest physical register allocated for the same logical register.
Archived from the original on 9 May When there are multiple instructions ready for the same functional unit, the oldest one is selected. This list is incomplete ; you can help by expanding it. Archived from the original on 23 October The highest frequency of Godson-3B is 1.

The Loongson 3 adds over new instructions over Loongson 2. In other projects Wikimedia Commons. The topic of the speech was “Research and Development of Godson processors”. Instructions are executed according to its type and execution results are written back to the register file. The four instructions in IR are decoded loogson the internal format and sent to the register renaming module. The manufacturer states that poongson user experience of the desktop solution has been significantly improved over its Loongson-3A based predecessor.
