Question 1 |
During the execution of the instructions, a copy of the instructions is placed in the .....
Register | |
RAM | |
System heap | |
Cache |
Question 2 |
Two processors A and B have clock frequencies of 700 Mhz and 900 Mhz respectively. Suppose A can execute an instruction with an average of 3 steps and B can execute with an average of 5 steps. For the execution of the same instruction which processor is faster?
A | |
B | |
Both take the same time | |
Insufficient information |
Question 2 Explanation:
The performance of a system can be found out using the Basic performance formula.
Question 3 |
A processor performing fetch or decoding of different instruction during the execution of another instruction is called .....
Super-scaling | |
Pipe-lining | |
Parallel Computation | |
None of the mentioned |
Question 3 Explanation:
Pipe-lining is the process of improving the performance of the system by processing different instructions at the same time, with only one instruction performing one specific operation.
Question 4 |
For a given FINITE number of instructions to be executed, which architecture of the processor provides for a faster execution?
ISA | |
ANSA | |
Super-scalar | |
All of the mentioned |
Question 4 Explanation:
In super-scalar architecture, the instructions are set in groups and they're decoded and executed together reducing the amount of time required to process them.
Question 5 |
The clock rate of the processor can be improved by .....
Improving the IC technology of the logic circuits | |
Reducing the amount of processing done in one step | |
By using the overclocking method | |
All of the mentioned |
Question 5 Explanation:
The clock rate(frequency of the processor) is the hardware dependent quantity it is fixed for a given processor.
