WebLittle Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.. It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a viable target for a C compiler.The language is less complex than x86 … WebLet's inspect the LD instruction in detail now. 0010 011 0 0000 0010. 0010: This is the opcode, if you want to use the LD instruction it will ALWAYS be this for the first 4. 011: This is the destination register, we are STORING a value into this register. In this case, 011(binary) = 3(decimal) so we are storing the value in Register 3(R3).
