An assembler translates assembly language to machine language instructions. A disassembler can be used to translate the other way, from machine language to assembly language. For example, our 8086 emulator shows both the machine language bytes and the disassembler output while running a program (it also shows the original assembly code). The disassembled code is usually harder to read than the original assembly language program because some things are missing or may be incorrect. Write down one of the things that may be missing or incorrect

Expert Solution

Assembler translates assembly language to machine language instructions and Disassembler translates machine language to assembly language. 8086 emulator shows both machine language bytes and disassembler output while running a program and it also shows the original assembly code.The disassembled code is difficult to read than the original assembly language program, because some things are missing or it may be incorrect. The missing terms in disassembly code is constants and comments.

Disassembler is actually the inverse of assembler. The output of disassembler is often formatted for human readablilty.

Because when an assembly language is converted into machine language by an assembler,constants and comments are removed from the assembled machine language. So when a disassembler works on these machine language ,it produce an assembly code which lacks constants ad comments User defined textual identifiers such as variables,labels and macros are removed by the assembler. These comments made the program easy t o understand and it gives some information about the purpose of the code.

In disassembler it is difficult to separate code from data. Data may be inserted into the code section or code may be inserted in the data section. It is not possible for all input programs.

Translate the C function code below to the MIPS True Assembler Language code (machine instructions only)....

Translate the C function code below to the MIPS True Assembler Language code (machine instructions only). The function code should follow the conventions for MIPS function calls including passing parameters and returning results. Your function code must be written with the minimum number of machine instructions to be executed and without any use of MIPS pseudo-instructions. Myfunction(unsigned int a, unsigned int b, unsigned int c) { int i=0; while (a > c) { a /= b; i++; } return i;...

Translate the following C code into M4K assembly language. You do not have to use the frame pointer, just use $sp if you need to use the stack. You do not have to show the stack initialization nor stack cleanup. If you need a specific value for an address, just make an assumption. int A; main() { int B = 5; B = A+B }; // main //Disassembly starts here !main() { //stack and frame pointer init // you do...
