Description: The synchronous 8051 microcontroller is a common processor found in many
embedded systems. By using asynchronous design techniques, the performance of the
8051 microcontroller is increased. Through simulation and the use of existing
synchronous design tools in the asynchronous design flow, a four-phase handshaking
approach with a stoppable clock is simulated and then implemented. The asynchronous
architecture added to the existing synchronous architecture includes an ALU wrapper, a
controller wrapper, and a clocking element. The asynchronous design flow consists of
functional simulation, synthesis of synchronous blocks, timing analysis, asynchronous
wrapper design, and timing simulation. After implementation analysis, the asynchronous
8051 is 28.7 faster then the synchronous 8051 while only using 10 more area.
