Archived from the original on 21 June 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. The manufacturer states that the user experience of the desktop solution has been significantly improved over its Loongson-3A based predecessor. Loongson is the result of a public—private partnership.

In other projects Wikimedia Commons. This desktop solution uses an optimized version of Fedora 13, with a lot of software ported and available, such as Kingsoft WPS office suite. The new instructions help with emulation performance, for example QEMU the only known example.

Four new instructions are sent to the instruction register IR if the instruction fetch is a TLB hit and a cache hit. It was formerly called Godson.

Loongson insiders [56] revealed a new model based on the Loongson 3A quad-core laptop has been developed and is expected to 2c in August The renamed instructions are latched to be sent to reservation stations and queues in next cycle. Open source applications on Linux Platform can be ported with little effort.


A ,oongson physical register is allocated for each logical destination register, and the logical source register is renamed according to the latest physical register allocated for the same logical register. The Loongson 2 adds bit ability to the Loongson architecture.

Intel Core 2 Duo P vs vs Loongson 2F MHz

Early implementations of the family lacked four instructions patented by MIPS Technologies to avoid legal issues. For the performance, because the frequency is only 1. Archived from the original on 4 June Results of a benchmark test, conducted in Aprilare available [14]. Each empty entry of reservation stations and queues selects among four dispatched instructions in this cycle. Archived from the original on 17 April InLoongson released latest version of 3A cpu, 3A Based in BeijingBLX focuses on designing the bit Loongson general-purpose and embedded processors, together with developing software tools and reference platforms.

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. Retrieved 26 May Archived from the original on 23 October Up to four instructions can be committed in program order per cycle.

Inter-instruction dependencies among four instructions mapped in the same cycle are also checked. This article’s use of external links may not follow Wikipedia’s policies or guidelines. Archived from the original on 15 September Marvell 88E “Link Street”.

Associated instructions are also sent to branch queue and memory queue. In SeptemberLemote announced the Yeeloong The highest frequency of Godson-3B is 1.

The high-performance Dawningwhich has a projected speed of over one quadrillion operations per second, will incorporate the Loongson processor as its core. Archived from the original on 9 May By using this site, you agree to the Terms of Use and Privacy Policy.

ICT has launched a Loongson-3B-based six-core desktop solution. They are also sent to the memory access queue to allow committed store instructions to write cache or memory.

One instruction with all required operands ready is selected from the fixed- or floating-point reservation station for each functional unit. Tag compare is also performed at this stage, but value selection according to tag compare result is delayed to next cycle.

Many operating systems work on Loongson: Each version can be clocked from 1. Broadcom various Cavium Octeon.
