LC-2K ISA

2019 HYU Computer Architecture PROJECT#1

Implementation

1. Assembler
2. Simulator
3. Multiplication Assembly Code

Develop Environment

• GCC
  • Apple LLVM version 10.0.1 (clang-1001.0.46.4)
  • Target x86_64-apple-darwin18.5.0
  • Debug with LLDB
• Visual Studio Code

Project Specifications

Assembler

• Assembler should catch the following errors in the assembly-language program: use of undefined labels, duplicate labels, offsetFields that don't fit in 16 bits, and unrecognized opcodes.
• Assembler should exit(1) if it detects an error and exit(0) if it finishes without detecting any errors.
• Assembler should NOT catch simulation-time errors
• The bounds of the numeric value for .fill instructions are -2^31 to +2^31-1 (-2147483648 to 2147483647).
• Register 0 will always contain 0
• Since offsetField is a 2's complement number, it can only store numbers ranging from -32768 to 32767

Simulator

• The LC-2K is an 8-register, 32-bit computer.
• All addresses are word-addresses.
• The LC-2K has 65536 words of memory

Multiplication

• Input the numbers by reading memory locations called "mcand" and "mplier"
• You may assume that the two input numbers are at most 15 bits and are positive.
• Remember that shifting left by one bit is the same as adding the number to itself.
• Submit a version of the program that computes (32766 * 10383)
• it must be at most 50 lines long and execute at most 1000 instructions for any valid input

Build & Run
