During the execution of the instructions, a copy of the instructions is placed in the ______
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 ?
Explanation: The performance of a system can be found out using the Basic performance formula.
A processor performing fetch or decoding of different instruction during the execution of another instruction is called ______
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.
For a given FINITE number of instructions to be executed, which architecture of the processor provides for a faster execution ?
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.
The clock rate of the processor can be improved by _________
Explanation: The clock rate(frequency of the processor) is the hardware dependent quantity it is fixed for a given processor.
An optimizing Compiler does _________
Explanation: An optimizing compiler is a compiler designed for the specific purpose of increasing the operation speed of the processor by reducing the time taken to compile the program instructions.
The ultimate goal of a compiler is to ________
SPEC stands for _______
Explanation: SPEC is a corporation started to standardize the evaluation method of a systems performance.
As of 2000, the reference system to find the performance of a system is _____
Explanation: In SPEC system of measuring a systems performance, a system is used as a reference against which other systems are compared and performance is determined.
When Performing a looping operation, the instruction gets stored in the ______
Explanation: When a looping or branching operation is carried out the offset value is stored in the cache along with the data
If a processor clock is rated as 1250 million cycles per second, then its clock period is ________
The average number of steps taken to execute the set of instructions can be made to be less than one by following _______
Explanation: The number of steps required to execute a given set of instructions is sufficiently reduced by using super-scaling. In this method a set of instructions are grouped together and are processed.
CISC stands for _______
Explanation: CISC is a type of system architecture where complex instructions are grouped together and executed to improve the system performance.
As of 2000, the reference system to find the SPEC rating are built with _____ Processor.
If the instruction, Add R1, R2, R3 is executed in a system which is pipe-lined, then the value of S is (Where S is term of the Basic performance equation)
Explanation: S is the number of steps required to execute the instructions.
