Abstract
An interface system for interfacing an asynchronous circuit with a synchronous circuit, wherein the synchronous circuit samples, in response to a clock signal, a first data signal when a first control signal indicates that the first data signal contains valid data, and wherein the asynchronous circuit generates a second data signal according to an asynchronous communication protocol. The system includes a FIFO memory, a control circuit for asynchronously writing the second data signal in the memory when the second data signal indicates the start of a communication, and synchronously reading the second data signal from the memory in response to a clock signal, and a conversion circuit for decoding, according to a asynchronous communication protocol, the second data signal read from the memory in a decoded data signal, wherein the decoded data signal corresponds to the first data signal.
