The value is then sent to memory access queue, where dynamic memory disambiguation and memory forwarding is performed. Views Read Edit View history.

The manufacturer states that the user experience of the desktop solution has been significantly improved over its Loongson-3A based predecessor. Many operating systems work on Loongson: Four new instructions are sent to the instruction register IR if the instruction fetch is a TLB hit and a cache hit. Result buses are also sent to the reservation station for snooping and to the register mapping table to lokngson that the associated physical register is ready.

Archived from the original on Archived from the original on 15 September For the performance, because the frequency is only 1. Tag compare is also performed at this stage, but value selection according to tag compare result is delayed to next cycle.


When there are multiple instructions ready for the same functional unit, the oldest one is selected. Inter-instruction dependencies among four instructions mapped in the same cycle are also checked. One instruction with all required operands ready is selected from the fixed- or floating-point reservation station for each functional unit.
