Storage unit for communication system node, method for data storage and communication system node

A data storage device within a communication system, for configuration and buffering related data that is provided outside of a communication controller on a system level, wherein the communication system is provided with active time slots and at least one logical buffer, the data storage device comprising:

• a slot control list to associate communication controller time slots to their respective buffers;
• a buffer control list, wherein a buffer control list offset is in a slot control list entry;
• a buffer descriptor list, wherein a buffer descriptor list offset is in a buffer control list entry;
• and a frame buffer that holds at least frame data.

A method for data storage for control and buffering related data within a communication system for time-triggered communication protocols, comprising:

• addressing an entry of a slot control list through a communication controller;
• linking the slot control list entry to a buffer control list entry to associate a time slot to a buffer, wherein a buffer control list offset is in the slot control list entry;
• addressing the buffer control list entry through said communication controller;
• linking the buffer control list entry to a buffer descriptor list entry to associate the buffer to the buffer descriptor list entry, wherein a buffer descriptor list offset is in the buffer control list entry;
• addressing the buffer descriptor list entry through said communication controller;
• linking said buffer descriptor list entry to a frame buffer;
• and addressing the frame buffer through said communication controller.
