Method and system for data transactions on a communications interface

Abstract

A system-on-a-chip (SoC) with one or more processors and other system components may have one or more peripheral component interconnect express (PCIe) physical connections between the processors and other system components to provide agent-to-agent communication. The agents on the communication fabric of the SoC may transmit data through the hardware PCIe interface where a transmitter device of an agent or digital logic component receives at least one data block for transmission and receives a flag corresponding to the at least one data block. The transmitter device may then send, via a PCIe physical layer, the received data blocks as a payload of a packet based on the flag, where the packet has a PCIe compliant header. The payload of the packet with the PCIe header may be entirely composed of these data blocks or flits from the agent.
