Pipelined buffer interconnect

A method and system to transfer data from one or more data sources to one or more data sinks using a pipelined buffer interconnect fabric is described. The method comprises receiving a request for a data transfer from the data source to the data sink, assigning a first buffer and a first bus to the data source, locking the first buffer and the first bus so as to enable only the data source to transfer data to the first buffer via the first bus, receiving a signal from the data source indicating completion of data transfer to the first buffer, unlocking the first buffer and the first bus, assigning the first buffer and the first bus to the data sink, assigning a second buffer and a second bus to the data source, locking the second buffer and the second bus so as to enable only the data source to transfer data to the second buffer via the second bus and enabling the data sink to read data from the first buffer via the first bus while the data source writes to the second buffer via the second bus, thereby pipelining the data transfer from the data source to the data sink. The transfer of data from data source to data sink is controlled by programming the pipelined buffer interconnect via one or more of software, control registers and control signals.
