8051 is a term for Intel's MCS-51 single chip microcontroller (MCU). It was one of the first microcontrollers ever. The instruction set is still in use in a lot of modern designs. Modern implementations are usually "pipelined" and execute a single instruction in a single cycle, so they are much faster than the original design. |
