Archived from the original on 15 September Loongson is the result of a public—private partnership. 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. Based in BeijingLoongspn focuses on designing the bit Loongson general-purpose and embedded processors, together with developing software tools and reference platforms.

Early implementations of the family lacked four instructions patented by MIPS Technologies to avoid legal issues. Loongsson version can be clocked from 1.

The topic of the speech was “Research and Development of Godson processors”. For the performance, because the frequency is only 1. Archived from the original on 23 April In other projects Wikimedia Commons. Many operating systems work on Loongson: They are also sent to the memory access queue to allow committed store instructions to write cache or memory.

Instructions are executed according to its type and execution results are written back to the register file. The issued instruction reads its source operands from the physical register file and is sent to the associated functional units. June Learn how and when to remove this template looongson.

Retrieved 31 May 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 new instructions help with emulation performance, for example QEMU the only known example. From Wikipedia, the free encyclopedia. Views Read Edit View history. This list is incomplete ; you can help by expanding it. Inter-instruction dependencies among four instructions mapped in the same cycle loongwon also checked.

The high-performance Dawningwhich has a projected speed of over one quadrillion operations per second, will incorporate the Loongson processor as its core.

Instructions with unready source operands snoop result and forward buses for their operands. InLoongson released latest version of 3A cpu, 3A It was formerly called Godson. Four new instructions are sent to the instruction register IR if the instruction fetch is 2v TLB hit and a cache hit.

Archived from the original on 23 October The Loongson 2 adds bit ability to the Loongson architecture.

Archived from the original on 13 April 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. 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.

One instruction with all liongson operands ready is selected from the fixed- or floating-point reservation station for each functional unit.
