One embodiment of the present invention provides a system for controlling asynchronous data transfers within a circuit. This system operates by monitoring a first voltage level on a first conductor that specifies whether a first stage of the circuit contains data. The system also monitors a second voltage level on a second conductor that specifies whether a second stage of the circuit contains data. Upon detecting that the first voltage level indicates that first stage contains data to be transmitted to the second stage, and that the second voltage level indicates that the second stage does not contain data, and is therefore available to receive data from the first stage, the system transfers the data from the first stage to the second stage. This is accomplished by generating a second stage latch signal to latch data into the second stage from the first stage. It also involves changing the first voltage level to indicate that the first stage no longer contains data, and changing the second voltage level to indicate that the second stage contains data.
