Definition: Microprogrammed is a term used in computer science to describe an instruction set that can be executed by a single CPU core. It refers to a subset of instructions, or "microinstructions," that are typically performed by one or more processors simultaneously, rather than being processed sequentially as in traditional microprocessors. These microinstructions can include both arithmetic and control operations, making them versatile for tasks such as data manipulation, memory access, and system management. The term was originally used to describe the instruction set of
