Question

Stack is a useful storage component for handling nested procedure calls. True False b) The larger number of registers a processor has, the higher is its speed? True False c) The larger is number of segments in an instruction pipeline: the lower is the processor speed? True False d)Arithmetic operations of unsigned numbers take less time than arithmetic operations of signed numbers? True false e) Flowchart and its corresponding hardware block diagram for multiplying two 2's complement numbers is the same as flowchart and its corresponding hardware block diagram for multiplying two signed magnitude numbers. True False

Explanation / Answer

a) TRUE

For handeling nested procedure calls stack can be usefull. When a procedure is called the current procedure is put in the top of the stack and new procedure execution will start.

b) FALSE

Processor Speed doesn't depends on the number of registger a processor has after a certain level. Processor speed depends upon the computation power i.e clock frequency. Also increasing registers will increase the instruction code length and more coputatiion will be required which will overall decrease speed.

c) TRUE

Because some time required for buffer the result and also each stage can never be of equal length to make it equal all stages have to give execution time with maximum execution time of a stage. Hence single stage time will increase but overall performance will be enhanced

d)FALSE

Because no difference from CPU point of view it's just change of logics ultimately cpu has to perform same computations so no difference in time upto logic calculation takes the same amount of time.
