Data movement instructions: The different instructions are been grouped as “instruction classes”. The instructions in a class performs same operation but with different sizes of operand. The “Mov” class denotes data movement instructions that copy data from a source location to a destination. The class has 4 instructions that includes: movb: It copies data from a source location to a destination. It denotes an instruction that operates on 1 byte data size. movw: It copies data from a source location to a destination. It denotes an instruction that operates on 2 bytes data size. movl: It copies data from a source location to a destination. It denotes an instruction that operates on 4 bytes data size. movq: It copies data from a source location to a destination. It denotes an instruction that operates on 8 bytes data size. Unary and Binary Operations: The details of unary operations includes: The single operand functions as both source as well as destination. It can either be a memory location or a register.

The “ja” instruction denotes “jump if above”. The comparison operation is performed. If result of comparison is greater, then jump operation takes place. The “pop” instruction resumes execution of jump instruction. The “jmpq” instruction jumps to given address. It denotes a direct jump.

Chapter 4.5, Problem 4.37PP

Program Plan Intro

Data movement instructions:

The different instructions are been grouped as “instruction classes”.

The instructions in a class performs same operation but with different sizes of operand.

The “Mov” class denotes data movement instructions that copy data from a source location to a destination.

The class has 4 instructions that includes:

movb:

It copies data from a source location to a destination.

It denotes an instruction that operates on 1 byte data size.

movw:

It copies data from a source location to a destination.

It denotes an instruction that operates on 2 bytes data size.

movl:

It copies data from a source location to a destination.

It denotes an instruction that operates on 4 bytes data size.

movq:

It copies data from a source location to a destination.

It denotes an instruction that operates on 8 bytes data size.

Unary and Binary Operations:

The details of unary operations includes:

The single operand functions as both source as well as destination.

It can either be a memory location or a register.

The instruction “incq” causes 8 byte element on stack top to be incremented.

The instruction “decq” causes 8 byte element on stack top to be decremented.

The details of binary operations includes:

The first operand denotes the source.

The second operand works as both source as well as destination.

The first operand can either be an immediate value, memory location or register.

The second operand can either be a register or a memory location.

Jump Instruction:

The “jump” instruction causes execution to switch to an entirely new position in program.

The “label” indicates jump destinations in assembly code.

The “je” instruction denotes “jump if equal” or “jump if zero”.

The comparison operation is performed.

If result of comparison is either equal or zero, then jump operation takes place.

The “ja” instruction denotes “jump if above”.

The comparison operation is performed.

If result of comparison is greater, then jump operation takes place.

The “pop” instruction resumes execution of jump instruction.

The “jmpq” instruction jumps to given address. It denotes a direct jump.

Prove for each pair of expression f(n) and g(n) whether f(n) is big O, little o Ω,ω or Θ of g(n). Use limits to find these. For each case it is possible that more than one of these conditions is satisfied:1. f(n) =log(n2^n), g(n) = log(sqrt(n)2^(n^2))2. f(n) =nsqrt(n) +log(n^n), g(n) =n + sqrt(n)logn

Need this expression solved for mu. This can be done using a symbolic toolbox, however it needs to end up being mu = function (theta, m, L, g). If using MATLAB or something similar, run the code to make sure it works.
