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. WebInterrupt tail-chaining. An external Non-Maskable Interrupt (NMI). An optional Wake-up Interrupt Controller (WIC). Late arriving interrupts. The processor automatically stacks its state on exception entry and unstacks this state on exception exit, with no instruction overhead. This provides low latency exception handling.
