LC-3 is a low-level programming language designed for teaching computer science. It was developed by Dr. Joel Adams and Dr. Sanjay Patel at Calvin College.
LC-3 is based on the Little Computer 3 (LC-3), a 16-bit microprocessor designed by James L. Peterson in 1985. The LC-3 is a popular choice for computer science education because it is simple enough to be easily understood by students, but is still capable of running complex programs.
The LC-3 instruction set includes just over 50 instructions, which are simple enough to be implemented in hardware without the need for a microcode ROM. This makes the LC-3 easy to design and build, and also easy to teach.
LC-3 is a assembly language, which means that programs are written in a text editor and then assembled into machine code, which can be run on the LC-3. Assembly language is a low-level programming language, which means that it is close to the machine code that the LC-3 runs. This makes it easy to understand what the LC-3 is doing, but it also makes it difficult to write complex programs.
LC-3 is a von Neumann architecture, which means that it has a single shared memory space for both code and data. This makes it easy to write programs that modify themselves, but it also makes it difficult to write programs that need to access multiple memories.
LC-3 is a Harvard architecture, which means that it has separate memory spaces for code and data. This makes it easy to write programs that access multiple memories, but it also makes it difficult to write programs that modify themselves.
LC-3 is a RISC architecture, which means that it has a small number of instructions that are executed very quickly. This makes the LC-3 fast, but it also makes it difficult to write programs that need to do complex operations.
LC-3 is a CISC architecture, which means that it has a large number of instructions that are executed slowly. This makes the LC-3 slow, but it also makes it easy to write programs that need to do complex operations.
LC-3 is an 8-bit microprocessor, which means that it can store and process 8-bit numbers. This makes the LC-3 limited in the size of numbers it can store and process, but it also makes it easy to work with bytes of data.
LC-3 is a 16-bit microprocessor, which means that it can store and process 16-bit numbers. This makes the LC-3 limited in the size of numbers it can store and process, but it also makes it easy to work with words of data.
LC-3 is a 32-bit microprocessor, which means that it can store and process 32-bit numbers. This makes the LC-3 limited in the size of numbers it can store and process, but it also makes it easy to work with doublewords of data.
The LC-3 has a small number of registers, which are used to store data and memory addresses. The LC-3 has eight general-purpose registers, which can be used to store data. The LC-3 also has two special-purpose registers, which are used to store memory addresses.
The LC-3 has a limited number of addressing modes, which are used to calculate memory addresses. The LC-3 has five addressing modes: immediate, register direct, register indirect, auto-increment, and auto-decrement.
The LC-3 has a limited instruction set, which is a small set of instructions that can be executed by the LC-3. The LC-3 has just over 50 instructions, which are simple enough to be implemented in hardware without the need for a microcode ROM.
The LC-3 is a simple microprocessor, which makes it easy to understand and teach. The LC-3 is also fast and capable of running complex programs.
