Abstract
Data transmission memory (1) for the transmission of data packets between subscribers T with a pointer address memory (2) for storing chained subscriber-pointer address lists, comprising pointer addresses, for each subscriber; a plurality of subscriber state registers (12), which in each case store the state of an associated subscriber-pointer address list; a data memory (3) for storing data blocks which can be addressed by the pointer addresses; and with a memory controller (4) for controlling the pointer address memory (2) and the data memory (3).
Claims18
A method of controlling a data transmission memory for the transmission of data packets between subscribers comprising the steps of storing, for each subscriber in a pointer address memory, a chained subscriber-pointer address list with address pointers for addressing data memory blocks of a data memory, wherein each said data memory block comprises a plurality of data memory cells;
- and storing said subscriber-pointer address list, a beginning address pointer to the last memory block, the number of data memory blocks and a filling level of the last data memory block in a subscriber state register;
- and said controlling the transmission of data packets between the subcribers based on stored information in the memory.
