(n.) Overlapping the execution of two or more operations. Pipelining is used within processors by prefetching instructions on the assumption that no branches are going to preempt their execution; in vector processors, in which application of a single operation to the elements of a vector or vectors may be pipelined to decrease the time needed to complete the aggregate operation; and in multiprocessors and multicomputers, in which a process may send a request for values before it reaches the computation that requires them. See also architecture.
(n.) A hardware feature enabling operations to reduce to multiple stages, each of which takes (typically) one cycle to complete.
A method of execution which allows each step of an operation to pass its result to the next step after only one clock period.
A process in which instruction execution takes place in a series of units, arranged so that several units can be simultaneously processing the appropriate parts of several instructions
It is a kind of technique used whereby the second instruction begin executing before the first one is even completed. Hence, resulting in cases such that several instructions are being executed in the pipeline, each of them at a different processing stage.
splitting the CPU into a number of stages, which allows multiple instructions to be executed concurrently. [SILC99
Pipelining is the decomposition of a computation into operations which may then be executed concurrently. Pipelining increases the utilization of functional units in the processor, leading to greater computational throughput. Common microprocessors have between four and twenty pipeline stages.
Two sets of threads serve as producers and consumers. While producers put data in a shared buffer, consumers can process the data in the shared buffer concurrently.
An advanced microprocessing technique in which the server handles several stages of different instructions at one time.
A CPU feature designed to begin processing a new instruction as soon as the previous instruction completes the first stage of the machine cycle.
an implementation technique whereby multiple instructions are overlapped in execution
Overlapping the execution of two or more operations. Pipelining typiclly involves starting one operation, then immediately starting the other without having to wait for the first to complete. It applies the principle of the multi-stage production line to computer processors.
A technique commonly used in high performance microprocessors that allows an instruction to begin execution before previous ones have been completed.
Process of the processor beginning to execute a second instruction before it completes the first instruction, which results in faster processing because the processor does not have to wait for one instruction to complete the machine cycle before fetching the next. 4.7
improves system performance by allowing the CPU to begin executing a second instruction before the first is completed. A pipeline can be likened to an assembly line, with a given part of the pipeline repeatedly executing a set part of an operation on a series of instructions.
The process of starting or issuing the next instruction prior to the completion of the instruction that is currently executing (e.g., while one instruction is being executed, another instruction is being fetched). This allows the execution of one instruction per clock cycle in order to improve the processor's performance.
In computers, a pipeline is the continuous and somewhat overlapped movement of instruction to the processor or in the arithmetic steps taken by the processor to perform an instruction. Pipelining is the use of a pipeline. Without a pipeline, a computer processor gets the first instruction from memory, performs the operation it calls for, and then goes to get the next instruction from memory, and so forth. While fetching (getting) the instruction, the arithmetic part of the processor is idle. It must wait until it gets the next instruction. With pipelining, the computer architecture allows the next instructions to be fetched while the processor is performing arithmetic operations, holding them in a buffer close to the processor until each instruction operation can be performed. The staging of instruction fetching is continuous. The result is an increase in the number of instructions that can be performed during a given time period.
A technique in which memory loads the requested memory contents into a small cache composed of SRAM, then immediately begins fetching the next memory contents. This creates a two-stage pipeline, where data is read from or written to SRAM in one stage, and data is read from or written to memory in the other stage.
Segmenting a functional unit such that it can accept new operands every cycle while the total execution of the instruction may take many cycles. The pipeline construction works like a conveyor belt accepting units until the pipeline is filled and than producing results every cycle.
A technique used in advanced microprocessors where the microprocessor begins executing a second instruction before the first has been completed. That is, several instructions are in the pipeline simultaneously, each at a different processing stage
A process to speed up the throughput of a microprocessor by staging different jobs to run concurrently rather than doing them in sequence.
Pipelining is a technique used in many microprocessors to improve performance. With pipelining, a microprocessor can begin executing a second instruction before it has finished with the first. A pipeline is split into segments and each segment can execute its operation at the same time as the other segments. Usually, the more advanced a pipeline is the more segments it has.
The execution of a sequence of data sets by a single processor in such a way that subsequent data elements or instructions in the sequence can begin execution before previous elements have completed execution, with all such elements executing at the same time; an assembly line approach. In vector supercomputers the floating-point operations were often pipelined with memory fetches and stores of the vector data sets. (The Denelcor HEP is an example of a pipelined instruction set; the Japanese supercomputers, the IBM 3090/VF, CRAY and Cyber 200 series are examples of pipelined arithmetic units.)
This process is used by computer processors to speed up the processing of data. A processor begins executing the next command before the first command has been completed.
