Bridge Circuit Buffer for Heterogeneous Signal Synchronization

A bridge circuit is introduced as an intermediary component between the FPGA apparatus and virtual platform. The bridge circuit includes a first interface connected to the FPGA, a second interface connected to the virtual platform, and a buffer unit that temporarily stores data transmitted from the FPGA. This mediator resolves the speed mismatch by decoupling the two platforms, allowing the faster FPGA to transmit data without waiting for the slower virtual platform, thus maintaining signal synchronization while preserving the productivity benefits of heterogeneous platforms

The bridge circuit dynamically adjusts the signal transmission bandwidth parameter based on the actual speed differences between platforms. By changing the bandwidth parameter adaptively rather than using a fixed high-bandwidth connection, the system achieves synchronization without permanently increasing system complexity. The bandwidth adjustment is performed only when needed to match timing requirements

The buffer unit serves as a simple intermediary storage element that temporarily holds data from the FPGA before forwarding it to the virtual platform. This minimal buffer structure provides the necessary timing adjustment and data accuracy without creating complex processing logic. The buffer simply stores and forwards data, avoiding the need for complex control mechanisms while still improving data transmission accuracy
