Pipeline Processing
Pipelining is a process to realize, overlapped parallelism in the proposed answer of a problem, on a digital computer in an economical way. To understand the concept of pipelining, we need to understand first the concept of assembly lines in an automated production plant where items are assembled from separate parts (stages) and output of one stage becomes the input to different stage. Taking the analogy of assembly lines, pipelining is the method to introduce temporal parallelism in computer operations. Assembly line is the pipeline and the separate parts of the assembly line are different stages through which operands of an operation are passed.
To introduce pipelining in a processor P, the following steps given below:
In this way, parallelism in a pipelined processor can be achieved like that m independent operation can be present simultaneously in m segments as shown given below:-
The phases or section are executed as pure combinational circuits performing logic or arithmetic operations over the data streams flowing through the pipe. Latches are used to divide the phases, which are quick registers to hold intermediate results among the phases as shown in Figure. Each phase Si consists of a processing circuit Ci and a latch Li . The last output is stored in output register R. The flow of data vary from one stage to another is controlled by a common clock. Therefore, in every clock period, one stage transmits results to another stage.
Define Top-down parsing Techniques Top-down parsing can be observed as an attempt to find left-most derivations of an input-stream through searching for parse trees using a top
Zero address instruction format is used for (A) RISC architecture. (B) CISC architecture. (C) Von-Neuman architecture. (D) Stack-organized architecture.
The process of entering data into a ROM is called ? Ans. The process of entering data in ROM is termed as programming the ROM.
Elements are given 3,14,7,1,8,5,11,17,,6,23,12,20,26,4,16,18,24,25,19 We will construct b tree and avl tree And after that delete some integers
Different sorting algorithm will be discussed in the lecutres. The task in this worksheet is to write a funtions based on the Quicksort algorithm. When sorting an array of objec
Define speculative execution. Speculative execution means that instructions are implemented before the processor is particular that they are in the correct execution sequence.
When can a user program execution be interrupted? It won't be desirable to interrupt a program when an instruction is being executed and is in a state such as instruction decod
