LC-3b Project Source Code
Stage 1 - LC-3b Assembler
Translates assembly language source code into the machine language (ISA) of the LC-3b.
Stage 2 - Instruction Simulator
Takes as input a file which is an assembled LC-3b program. The simulator then executes the input LC-3b program, one instruction at a time, modifying the architectural state of the LC-3b after each instruction. The simulator is partitioned into two main sections: the shell and the simulation routines.
Stage 3 - Cycle-Level Simulator
A cycle-level simulator for the LC-3b. The simulator takes two inputs: a file entitled ucode3 which holds the control store, and a file which is an assembled LC-3b program. The simulator executes the input LC-3b program, using the microcode to direct the simulation of the microsequencer, datapath, and memory components of the LC-3b.
Stage 4 - Pipelined Simulator
The final part of the simulator involved building a pipelined simulator for the LC-3b instruction set which executes the program in a parallel/pipelined fashion.
