In SeptemberLemote announced the Yeeloong When there are multiple instructions ready for the same functional loongsson, the oldest one is selected. Retrieved 16 April June Learn how and when to remove this template message. InLoongson released latest version of 3A cpu, 3A From Wikipedia, the free encyclopedia. Loongsson from the original on 23 October Archived from the original on 4 June Early implementations of the family lacked four instructions patented by MIPS Technologies to avoid legal issues.
Archived from the original on 17 April Retrieved 31 May Open source applications on Linux Platform can be ported with little effort.

The Loongson 3 adds over new instructions over Loongson 2. Each version can loonyson clocked from 1. It may also get the data directly from one of the result buses if its source register number matches the destination register number of the result bus. Up to four instructions can be committed in program order per cycle. Most common open-source applications including OpenOffice.
Associated instructions are also sent to branch queue and memory queue. This article’s use of external links may not follow Wikipedia’s policies or guidelines. Archived from the original on 21 June It is fabricated with 0.
Inter-instruction dependencies among four instructions mapped in the same cycle are also checked. The highest frequency of Godson-3B is 1. Each empty entry of reservation stations and queues selects among four dispatched instructions in this cycle.
The four instructions in IR are decoded in the internal format and sent to the register renaming module.
Loongson is the result of a public—private partnership. Renamed instructions are dispatched to the fixed- or floating-point reservation station to be executed, and are sent to the reorder queue for in-order graduation.
The value is then sent to memory access queue, where dynamic memory disambiguation and memory loonson is performed.

Instructions with unready source operands snoop result and forward buses for their operands. Views Read Edit View history. Many operating systems work on Loongson: In AugustLoongson Technology Corp. The new instructions help with emulation performance, for lolngson QEMU the only known example. Wikinews has related news: Instructions are executed according to its type and execution results are written back to the register file.
They are also sent to the memory access queue to allow committed store instructions to write olongson or memory. Li Guojie, chairman of Dawning Information Industry Company and director and academician of the Institute of Computing Technology, said research and development of the Dawning is expected to be completed in two years. The renamed instructions are latched to be sent to reservation stations and queues in next cycle.

Result buses are also sent to the reservation station for snooping and to the register mapping table to notify that the associated physical register is ready.
