  • Patent number: 12149268
    Abstract: A terahertz full-duplex co-local oscillator solid-state front-end transmitting circuit is disclosed, which belongs to the technical field of terahertz communication. The overall structure of the solid-state front-end transmitting circuit adopts a new system, wherein the circuit comprises two branches that are parallel and driven by a local oscillator source. A branched waveguide directional coupler is configured to output two driving signals provided by the same local oscillator source respectively to two branch circuits with required powers. Two transmission signals generated from the two branches are combined into one signal for transmission through an orthogonal mode coupled duplexer, so as to fulfill the construction of a full-duplex co-local oscillator solid-state front-end transmission circuit.

  • Patent number: 12099377
    Abstract: A delay adjustment cell is disposed in a channel of at least one regional clock of a chip clock architecture, and the delay adjustment cell includes a plurality of parallel delay paths with different delay values. The delay adjustment cell gates one of the delay paths based on an obtained configuration signal such that a connected regional clock has a corresponding target delay, and a target delay of each regional clock corresponds to a clock skew mode of the programmable logic chip. A clock skew between different regional clocks is adjusted by controlling the gated delay path in the delay adjustment cell, such that a clock skew of the chip can be adjusted in a relatively large range. Under the same resource configuration, different path choices of the delay adjustment cell lead to different clock skews to meet different clock skew modes in different application scenarios.

  • Patent number: 12009307
    Abstract: The present application discloses a multi-die FPGA implementing a built-in analog circuit using an active silicon connection layer, and relates to the field of FPGA technology. The multi-die FPGA allows multiple small-scale and small-area dies to cascade to achieve large-scale and large-area FPGA products, reducing processing difficulties and improving chip production yields. Meanwhile, due to the existence of the active silicon connection layer, some circuit structures that are difficult to implement within the die and/or occupy a large die area and/or have a low processing requirement can be laid out in the silicon connection layer, solving the existing problems of making these circuit structures directly within the die. Part of the circuit structures can be implemented within the silicon connection layer and the rest in the die, which helps optimize the performance of FPGA products, improve system stability, and reduce system area.

    Abstract: An FPGA for implementing data transmission by using a built-in edge module is provided. The FPGA is provided with a built-in edge module. A read port of each resource module connected to the edge module in the FPGA is separately connected to a winding architecture and the edge module, and/or a write port of each resource module connected to the edge module in the FPGA is separately connected to the winding architecture and the edge module. The edge module includes a read/write controller and a cache unit. The read/write controller simultaneously reads data from read ports of a plurality of resource modules and temporarily stores the read data in the cache unit.

  • Publication number: 20230353500
    Abstract: A routing node scheduling method for an NOC in an FPGA is used when a plurality of input ports each have a data packet to be transmitted to a routing node at the same time. A scheduling controller within the routing node is used to enable each input port according to a predetermined scheduling order, and the routing node receives a data packet through the enabled input port. In addition, quantities of times at least two input ports are enabled are different in one scheduling cycle, which means that the scheduling controller implements biased scheduling control over each input port, allowing different input ports to transmit data packets at different frequencies. This can increase a quantity of times an input port with high communication importance is enabled, making a data packet at the input port be transmitted more timely and achieving better transmission efficiency. The scheduling method can well match transmission requirements of different services to achieve optimal transmission performance of an NOC.

  • Patent number: 11776915
    Abstract: The present disclosure discloses an FPGA device forming a network-on-chip by using a silicon connection layer. An active silicon connection layer is designed inside the FPGA device. A silicon connection layer interconnection framework is arranged inside the silicon connection layer. Bare die functional modules inside an FPGA bare die are connected to the silicon connection layer interconnection framework to jointly form the network-on-chip. Each bare die functional module and a network interface and a router that are in the silicon connection layer interconnection framework form an NOC node. The NOC nodes intercommunicate with each other, so that the bare die functional modules in the FPGA bare die without a built-in NOC network can achieve efficient intercommunication by means of the silicon connection layer interconnection framework, reducing the processing difficulty on the basis of improving the data transmission bandwidth and performance inside the FPGA device.
