The term quad buffering is the use of double buffering for each of the left and right eye images in stereoscopic implementations, thus four buffers total (if triple buffering was used then there would be six buffers). The command to swap or copy the buffer typically applies to both pairs at once, so at no time does one eye see an older image ...
Reorder Buffer (ROB) A structure that is sequentially (circularly) indexed on a per-operation basis, for instructions in flight. It differs from a history buffer because the reorder buffer typically comes after the future file (if it exists) and before the architectural register file. Reorder buffers can be data-less or data-ful.
Buffering is also needed to accommodate irregularities in the rates at which the application feeds items to the first stage and consumes the output of the last one. The buffer between two stages may be simply a hardware register with suitable synchronization and signalling logic between the two stages. When a stage A stores a data item in the ...
Compute the effective address when the base register is available, and place it in the load/store buffer If the instruction is a load then: execute as soon as the memory unit is available; Else, if the instruction is a store then: wait for the value to be stored before sending it to the memory unit
In computing, a memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction.
ILP is exploited by both the compiler and hardware, but the compiler also provides inherent and implicit ILP in programs to hardware by compile-time optimizations. Some optimization techniques for extracting available ILP in programs include instruction scheduling, register allocation/renaming, and memory-access optimization.
