What is the split transaction mechanism in PCIe?
The split transaction mechanism in PCIe is a method that breaks down a single long transaction into smaller segments. This allows the system to handle other transactions while waiting for the completion of the split transaction, reducing overall latency and improving efficiency.
It helps in managing large data transfers more effectively by allowing the PCIe bus to stay active and responsive. This mechanism enhances the overall performance of PCIe by minimizing delays and optimizing data throughput.
