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.
Draw the ISDN address structure and explain how the addressing works? Address Structure: The ISDN address structure is demonstrated in figure. ISDN number part has a maximum
Remember, the value of α is between 0 and 1. Now, let us put some values of α and compute the speed up factor for increasing values of number of processors. We get that the S(N) k
What are difference between latches and flipflops? Difference : Latches are level-sensitive, while, flipflops is edge sensitive. It means to say edge sensitive that O/p change
Define bus. When a word of data is transferred among units, all the bits are transferred in parallel over a set of lines called bus. In addition to the lines that take the data
What is the Gray equivalent of (25) 10 Ans. Gray equivalent of (25) 10 : The Decimal number 25 has binary equivalent as (00100101) 2 The left most bits (MSB) into gray
What are transmission bridges? A usual transmission bridge is demonstrated in figure. The series capacitance and the shunt inductances of the two relays give a high-pass filte
VuGen gives the facility to use multithreading. This enables more Vusers to be run pergenerator. If the Vuser is run as a process, the similar driver program is loaded into memory
If various load generators need to access the similar physical files, rather than having to remember to copy the files every time they change, each load generator can reference a c
Q. Show the ranges of Port numbers? Port numbers are divided into three ranges: Well-known ports are those from 0 through 1,023. Registered ports are those from
What is meant by context switch? Switching the CPU to another process requires saving the state of the old process and loading the saved state for the new process. This task i
