Abstract: Aspects of the disclosure are directed to hardware interconnects and corresponding devices and systems for non-coherently accessing data in shared memory devices. Data produced and consumed by devices implementing the hardware interconnect can read and write directly to a memory device shared by multiple devices, and limit coherent memory transactions to relatively smaller flags and descriptors used to facilitate data transmission as described herein. Devices can communicate less data on input/output channels, and more data on memory and cache channels that are more efficient for data transmission. Aspects of the disclosure are directed to devices configured to process data that is read from the shared memory device. Devices, such as hardware accelerators, can receive data indicating addresses for different data buffers with data for processing, and non-coherently read or write the contents of the data buffers on a memory device shared between the accelerators and a host device.
