Chapter 3.4, Problem 3.2PP
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.
- movb:

1. A. Convert the following C code into AT&T assembly:
x at 8(%ebp)
if (x>5){
X++;
}
else {
X--;
}
while (x<10){
x++;
}
B. Annotate each line of the assembly code to describe how it operates.
C. Write a goto version of the function (in C) that mimics how the assembly code program
operates.

Currently, memory is word-addressed and all memory accesses load or store a 16-bit value. For example, LDA Ox6502 loads a 16-bit value from address Ox6502 into register A. The change is to support additionally 8-bit accesses, thanks to an expanded machine language (already designed by a colleague) which now supports instructions such as: ; load 16 bits from addr 6502 into A ; load 8 bits from addr 6502 into A LDAW Ox6502 LDAB Ox6502 Outline, at a high level, how you would bring about this change in the CPU design, and mentioning any difficulties you expect to encounter.arrow_forward
