About EmuARM

EmuArm is an ARM ISA emulator. It can be used to write, execute, and debug programs written in the ARM and Thumb assembly languages. It has a graphical mode as well as a command line mode.

Features provided

In-built text editor to code and debug ARM code
Emulation support for the ARM ISA
Thumb ISA
Breakpoints to assist debugging the program
Easy console input for integers
Step Into, Step Over and Step Out functions to get detailed line-by-line execution information of the program

How to launch the GUI Version of EmuARM

enter the emuarm directory
to compile the source code : type ant compile on the terminal
to make the jar files : type ant jar on the terminal
to run the jar (emuArm.jar) that is created using GUI, simply type java -jar emuArm.jar

How to launch the Command Line Version of EmuARM

enter the emuarm directory
to compile the source code : type ant compile on the terminal
to make the jar files : type ant jar on the terminal
to run the jar (emuArm.jar) that is created, using an assembly file as input, simply type java -jar emuArm.jar -f=filename. We can either enter the absolute ore the relative path of the file. Eg. java -jar emuArm.jar -f=temp.s
to display the register, branch and memory tables in the output in command line mode, type -tables after -f=<filename>

Usage

You can type regular ARM assembly code, and EmuArm will recognize it. If you need to write Thumb code first put the directive .thumb on a separate line. EmuArm supports two more directives: .read and .print. The .read directive is used to read the value of a register from the command line.

For example you can write: .read r1

This statement will read in a value into the register r1 from the command line or the GUI console (similar to scanf in C).

The .print directive can be used to print the value of a register to the command line or the GUI console.

For example: .print r1

See the file example.s in this directory.
