Patent number: 12572499Abstract: A best efforts (BE) hardware remote direct memory access (RDMA) transport being performed by a smart network interface controller (NIC). Elements from RoCEv2 and iWARP are utilized in combination with extensions to improve flexibility and packet error recovery. Flexibility is provided by allowing RDMA roles to be individually specified. Flexibility is also provided by additional packet numbering options to allow interleaving of request and response messages at a packet boundary. Error recovery is improved by utilized new acknowledgement responses, SNAK provided for each new hole detected and RACK for each received packet after a SNAK. SNAK allows the indication of resource exhaustion at the receiver, causing entry into a recovery mode where only packets in a hole are transmitted until resources are recovered.Type: GrantFiled: March 14, 2024Date of Patent: March 10, 2026Assignee: DreamBig Semiconductor Inc.Inventors: David Arditti Ilitzky, Linghe Wang, Brian Hausauer

Publication number: 20260010493Abstract: A chiplet hub for interconnecting a series of connected chiplets and internal resources. An HBM is mounted on top of the chiplet hub to provide multiple party access to the HBM and to save System in Package (SIP) area. The chiplet hub can form system instances to combine connected chiplets and internal resources, with the system instances being isolated. One type of system instance is a private memory system instance with private memory gathered from multiple different memory devices. The chiplet hubs can be interconnected to form a clustered chiplet hub to provide for a larger number of chiplet connections and more complex system. A DMA controller can receive DMA service requests from devices other than a system hosted, including in cases where the chiplet hub is non-hosted.Type: ApplicationFiled: August 20, 2025Publication date: January 8, 2026Inventors: David Arditti Ilitzky, Brian S. Hausauer, Prasenjit Chakraborty, Steven S. Majors, Linghe Wang, Kenneth J. Clark, David J. Maguire
