Abstract
An interface receiver, which is part of an interface that allows the transfer of data between two incompatible I/O standards, includes a crossbar and a barrel shifter that can be implemented using multiplier-accumulator blocks. The crossbar reorders an incoming burst of data and writes the data into a larger data column where the data is barrel-shifted using multiplier-accumulator blocks and transferred out of the receiver when an end-of-packet is detected or the shifted data column as seen from outside the interface receiver is full.
