Chapter 11, Problem 17E

Explanation of Solution

Analysis of the sidebar:

• System performance is considered as one of main factor of a processor.
• It is used to determine the speed a problem can be solved.
• It is also used to determine the factors such as number of problems that can be allocated at particular amount of time and also the number of problems that can be handled by the processor.
• The speed of the CPU is a key factor that often decides the performance of the system.
• But this factor speed is applied only to identical architecture and which will be misled at many cases.
• A detailed analysis is made to arrive at a detailed decision for different architecture.
• The efficiency that is employed with the architecture plays an important role when considering the performance.
• The performance can be improved based on the way the code is written.

Guidelines to improve the performance by writing the efficient code:

• The branches that are not required necessarily are being removed.
  • It is used to indicate the implication of organizational and architectural.
  • It indicates the way how the branches are processed or being pipelined but it is being related to the code aspect in a higher order.
  • Any branching instruction that is given the work of the processor is to guess the predicted outcome and based on that the process is being added to the pipeline.
  • In case the output is not as predicted it could be a loss in overall efficiency.
• The iteration is considered to be over recursive.
  • It is related with aspect of coding
  • Recursion involves the procedure call greatly.
  • The process involved will be storing it with the instruction and then with the program counter stored on to the stack and by shifting the control of the address to new procedure call.
  • This type of process may require high time to process but may not require huge storage capacity...
