How Can Do Solve Your Assembly Language Homework Easily?
If you are working on assembly language and need assembly language assignment help, we can write code in assembly language or even provide an assembler if you have to write one.
The easiest way to write an assembler is to write it as a 2 pass assembler, during the first pass you calculate the address values to store in the symbol table. If you wish to write a 1 pass assembler you need to modify the symbol table to store a list of referenced locations along with any offset (so you can write SCREEN + 40, before you define SCREEN), and then when you find the definition you go back and fill in the code values.
You need to write a tokenizer, that splits the text into symbols, instructions and values. It is worth making $ff represent a hex value since hex values are more common in assembly language than normal programming languages. You should also discard all comments since they do not need processing. Add register aliases, so you can write SCORE EQUR D0 then move.w #30, SCORE which would be the same as move.w #30, D0. It helps when writing code to be able to use register aliases rather than having to keep track of which register is being used for what purpose. You could get as tokens “move” “.w” “#” “30” “SCORE”, you replace the register aliases with the actual register, so “SCORE” becomes “D0”. You then work out the addressing mode (in this case it is immediate value, register). There are around 10-20 different addressing modes depending on the processor. You look up the instruction and addressing mode in table that gives the encoding (which determines the number of bytes as well).
To encode the instruction you need to encode the values of the register, so on 68000 you have D0-D7, A0-A7 which means there are 16 in total and will fit in 4 bits, on Intel there are named registers and not all instructions have the same encoding.
We’ve had to program a few assemblers along with sample code that uses them, although most assembly languages assignments use a pre-existing assembler, it is informative to write your own. Macros are very useful when writing assembly language, as they can make common actions simpler to perform, for example setting up a stack frame and accessing variables.
We’ve completed assignments in 68000, MIPS, ARM, LC3, x86 and various other assembly languages for micro-controllers. Once you can program in one assembly language, it is easier to learn another as there are similarities and I personally have programmed in 8 different assembly languages, with published games on 3 different processors. Assembly language is the most complex of the programming languages to program, but it actually has the simplest syntax since there is very little of it. We’ve had assignments the involve replacing part of the bios, and another one that involved solving sudoku problems. So we can handle even highly complex assembly language programs.
