Overview of LC3 Emulator GPT
The LC3 Emulator GPT is designed to simulate the functionality of the LC3 (Little Computer 3) microarchitecture, a teaching tool used primarily in educational settings to help students learn about computer architecture and assembly language programming. This GPT can interpret and execute instructions from the LC3 assembly language, modifying a simulated machine state accordingly. It handles operations such as arithmetic calculations, logical operations, memory access, and control flow. For example, if given the binary code for an ADD instruction, the emulator calculates the sum of two registers or a register and an immediate value, then stores the result in a specified register, mimicking the operation of an actual LC3 processor.

Core Functions of LC3 Emulator GPT
Executing Instructions
ExampleFor instance, the command 'NOT R2, R3' flips all bits of the value in register R3 and stores the result in R2. This is useful for implementing bitwise logical negation.
ScenarioA student testing their understanding of bitwise operations could use this to verify the results of manual calculations.
Simulating Memory Operations
ExampleUsing 'LDR R1, R2, #5', the emulator loads into R1 the value from the memory address calculated by adding 5 to the content of R2.
ScenarioUseful in a lab setting where students are learning how pointers and memory addressing work in lower-level programming.
Control Flow Management
ExampleWith 'BRnzp #9', the emulator would change the program counter to a new location based on the condition codes set by the previous instruction. This facilitates branching and decision-making in programs.
ScenarioInstructors can demonstrate how conditional logic is implemented at the machine level, aiding students in understanding assembly level programming.
Target Users of LC3 Emulator GPT
Computer Science Students
These users often need to understand and practice low-level programming concepts. The emulator allows them to execute LC3 assembly language without needing physical hardware, making it easier to learn and debug programs.
Educators in Computing
Professors and teachers can use this tool to create interactive examples and exercises. They can demonstrate live how assembly code translates into operations on a simulated LC3 machine, enhancing the educational experience.
