Publication number: 20230370521Abstract: The embodiments herein describe a communication protocol (which can be implemented in hardware or software) that provides efficient recover packet loss and can transit large messages in a complex network environment. In one embodiment, each data packet contains an encoded universal sequence which is unique across the sends, which enables cross-sender loss recovery. A receiver can include a transmission control module that controls the receiving buffer and maintains the buffer status and the sender's status. The transmission control module stores incoming packets to the correct position in the receiving buffer and generates acknowledgement notifications. The transmission control module also handles packet loss and out-of-order receiving of the packets containing the transactions.Type: ApplicationFiled: May 12, 2022Publication date: November 16, 2023Inventors: Ji YANG, Haris JAVAID, Sundararajarao MOHAN, Gordon John BREBNER

Publication number: 20230367923Abstract: A simulation framework is capable modeling a hardware implementation of a reference software system using models specified in different computer-readable languages. The models correspond to different ones of a plurality of subsystems of the hardware implementation. Input data is provided to a first simulator configured to simulate a first model of a first subsystem of the modeled hardware implementation. The input data is captured from execution of the reference software system. The first simulator executing the first model generates a first data file specifying output of the first subsystem. The first data file specifies intermediate data of the modeled hardware implementation. The first data file is provided to a second simulator configured to simulate a second model of a second subsystem of the modeled hardware implementation. The second simulator executing the second model generates a second data file specifying output of the second subsystem.Type: ApplicationFiled: May 10, 2022Publication date: November 16, 2023Applicant: Xilinx, Inc.Inventors: Ji Yang, Haris Javaid, Sundararajarao Mohan

Publication number: 20230342151Abstract: Embodiments herein describe a hardware accelerator for a blockchain node. The hardware accelerator is used to perform a validation operation to validate one or more transactions before those transactions are committed to a ledger of a blockchain. The embodiments herein describe an out-of-order validation scheme where a collector is used to collect validated transactions out of order. Thus, if a validation pipeline has finished validating a later transaction before another validation pipeline has finished validating an earlier transaction, the pipeline can nonetheless send its results to the collector and retrieve another transaction from a scheduler. In this manner, the downtime for the validation pipelines is reduced or eliminated.Type: ApplicationFiled: April 26, 2022Publication date: October 26, 2023Inventors: Haris JAVAID, Ji YANG, Sundararajarao MOHAN

Patent number: 11743051Abstract: Embodiments herein describe a hardware accelerator for a blockchain node. The hardware accelerator is used to perform a validation operation to validate one or more transactions before those transactions are committed to a ledger of a blockchain. The blockchain may include multiple peer-nodes, each of which contains standard software running on a server or container. Instead of validating a block of transactions using software, the hardware accelerator can validate the transactions in a fraction of the time. The peer-node software then gathers the validation results from the hardware accelerator and combines the results with received block data to derive the block which is committed to the stored ledger.Type: GrantFiled: October 28, 2020Date of Patent: August 29, 2023Assignee: XILINX, INC.Inventors: Haris Javaid, Ji Yang, Sundararajarao Mohan, Gordon John Brebner

Patent number: 11657040Abstract: Embodiments herein describe a hardware accelerator (e.g., a network acceleration engine) for a blockchain machine or node. The hardware accelerator parses packets containing separate components of a block of transactions to generate data to perform a validation process. To avoid the latency that comes with using software, the embodiments herein describe a protocol processor in the hardware accelerator that parses the packets and prepares the data so it can be consumed by downstream components in the accelerator without software intervention. These downstream components can then perform a validation operation to validate one or more transactions before those transactions are committed (i.e., added) to a ledger of a permissioned blockchain.Type: GrantFiled: October 30, 2020Date of Patent: May 23, 2023Assignee: XILINX, INC.Inventors: Ji Yang, Haris Javaid, Sundararajarao Mohan, Gordon John Brebner

Patent number: 10740146Abstract: Embodiments herein describe techniques for executing VMs on hosts that include an accelerator. The hosts can use the accelerators to perform specialized tasks such as floating-point arithmetic, encryption, image processing, etc. Moreover, VMs can be migrated between hosts. To do so, the state of the processor is saved on the current host thereby saving the state of the VM. For example, by saving the processor state, once the data corresponding to the VM is loaded into a destination host, the processor can be initialized to the saved state in order to resume the VM. In addition to saving the processor state, the embodiments herein save the state of the accelerator on a FPGA. That is, unlike previous systems where tasks executed by the accelerator are discarded when migrating the VM, the state of the accelerator can be saved and used to initialize an FPGA accelerator in the destination host.Type: GrantFiled: February 10, 2017Date of Patent: August 11, 2020Assignee: XILINX, INC.Inventor: Sundararajarao Mohan
