Abstract: Systems, methods and apparatus are described that offer improved performance of a sensor bus. A first command is transmitted to devices coupled to a serial bus operated in a first mode in accordance with a first protocol to cause the serial bus to be operated in a second mode.

In the second mode, extra symbols inserted into a sequence of symbols transmitted on the serial bus prevent the occurrence of an unintended signaling state on the serial bus. Pulses transmitted on a wire of the serial bus in the second mode may have their duration limited such that a filter of a second device suppresses the limited-duration pulses.

Abstract: Method and apparatus for sending packets using optimized PIO write sequences without sfences. Sequences of Programmed Input/Output (PIO) write instructions to write packet data to a PIO send memory are received at a processor supporting out of order execution. The PIO write instructions are received in an original order and executed out of order, with each PIO write instruction writing a store unit of data to a store buffer or a store block of data to the store buffer. Logic is provided for the store buffer to detect when store blocks are filled, resulting in the data in those store blocks being drained via PCIe posted writes that are written to send blocks in the PIO send memory at addresses defined by the PIO write instructions. Logic is employed for detecting the fill size of packets and when a packet's send blocks have been filled, enabling the packet data to be eligible for egress.
