Abstract
Disclosed embodiments provide an interface circuit for the transfer of data from a synchronous circuit to an asynchronous circuit. Data from the synchronous circuit is received into a memory in the interface circuit. The data in the memory is then sent to the asynchronous circuit based on an instruction in a circular buffer that is part of the interface circuit. Processing elements within the interface circuit execute instructions contained within the circular buffer. The circular buffer rotates to provide new instructions to the processing elements. Flow control paces the data from the synchronous circuit to the asynchronous circuit.
