<p>A system for selecting one of two or more parallel planes of data is provided. The system includes a first data buffer that is connected to a first data bus that carries a stream of datagrams. The first data buffer receives and stores datagrams from the first data bus. The system also includes a second data buffer that is connected to a second data bus that carries a stream of datagrams. The second data buffer receives and stores datagrams from the second data bus. A selection controller connected to the first data buffer and the second data buffer analyzes the datagrams stored in the first and second data buffers, and selects one of the datagrams to be the primary datagram.</p> |
