Important Notes

• lc3bsim4.c – the C source code for your LC-3b simulator.
• ucode4 – the microcode file for your simulator
• dumpsim – the dumpsim file created as specified in Lab Assignment 4. (Updated: 04/08/2007) We have updated Lab Assignment 4 with a detailed description of how to generate the dumpsim file.
• int.asm, vector_table.asm, except_prot.asm, except_unaligned.asm, add.asm, and data.asm – the assembly language files for the interrupt service routine, the interrupt/exception vector table, the protection exception handler, the user program, and the data for .for locations xC000–xC013.
• int.hex, vector_table.hex, except_prot.hex, except_unaligned.hex, add.hex and data.hex – the machine code for the interrupt service routine, the interrupt/exception vector table, the protection exception handler, the user program, and the data for locations xC000–xC013.
• readme.txt or readme.ps or readme.pdf or readme.tar – a printable file showing the changes you have implemented in the datapath, state diagram, microsequencer and any additional logic. This file can be in the following formats: text, postscript, PDF or HTML with images. If you prefer to submit a hardcopy of your documentation, you can submit it in class on Monday April 9, 2007.

You may not submit more than 16 files for Lab 4.

Note: please confirm that your file compiles by running gcc -ansi lc3bsim4.c on any ECE linux machine (linux01–linux24.ece.utexas.edu) before submitting your program.

Before the deadline, you may resubmit any of the files without penalty. Every time you resubmit a file, the original file is overwritten.

Instructions For Submission

1. SSH into sunfire1 with the following command:

   
   ssh sunfire1.ece.utexas.edu

2. After typing your username and password, submit your files with the following command:

   
   submit-ee360n lc3bsim4.c ucode4 dumpsim

   This command will submit the first 3 files. The remaining files can be submitted by changing the filenames.

3. You may check the files submitted with the following command:

   
   submit-ee360n -ls

Note: currently the submit script works only on sunfire.
