Shared memory packet interface
WebbThe Simulink interface is not aware of structures; pass the output of each structure segment as input to the Shared Memory Pack block. Memory partitions consist of groups of Simulink signals, which are combined into blocks (packets) of 32-bit words. Before you begin to configure this block, be sure that you have a predefined shared memory ... WebbThis L3 Ethernet Switch/Router IP core is built around a shared buffer memory architecture providing wire-speed switching and routing on all ports without head of line blocking. It offers dynamic allocation of packet buffers per port and priority to avoid starvation due to over-allocation. Advanced QoS features allow the most timing critical ...

WebbLANL used a shared memory layer to pass data to the ActiveX/EPICS inter-face just in case one wanted to switch to a different EP-ICS interface.

As the plugin is using PACKET_ADD_MEMBERSHIP to enter the promiscuous mode without interfering others, the PROMISC flag is not touched. To verify that the interface entered promiscuous mode you can use dmesg.
