Web5 mei 2024 · However, there is a trade-off between latency and throughput from the perspective of an Ethernet controller. To achieve lower latency, the controller usually minimizes the interval between interrupts to speed up small packet processing at the price of causing higher CPU usage and lower throughput. WebThe Low Latency Interface (LLI) is a point-to point-interconnect that allows two devices on the separate chips to communicate as if a device attached to or present on the remote chip is resident on the local chip. The connectivity to the remote chip’s devices is through standard interconnects (AHB/AXI/OCP), using memory mapped transactions.
