The PSI-L allows multiple independent streams of packet data (threads) to share a single interface using data phase granularity time division multiplexing. This time division multiplexing is accomplished by dividing each stream into single data transfers. In this way a stream is comprised of a sequence of strongly ordered data transfers but packet transfers between different streams are allowed to be interleaved. Each data phase is qualified with a type identifier which indicates whether the data is packet info, direct IO write or read info, timestamp, software info, control data, payload data, or status.
