THE REORDERING BUFFER ARCHITECTURE FOR LAYER OF ZIGBEE

摘要

A rearrangement transmission buffer structure of a ZigBee MAC(Medium Access Control) layer is provided to enable an ATT ATT(Address Translation Table) to take charge of a function of converting a logical address of a buffer into a physical address by comprising the in a general memory structure, thereby realizing an effective retransmission buffer. A unit installs an ATT in a memory structure so that the ATT takes charge of a function of converting a logical address of a buffer into a physical address, to realize a retransmission buffer. A unit forms 4 spaces of 1 byte of a memory into one segment, and connects the formed segment to one physical address and logical address. When size of the addresses is defined according to size of the memory, the ATT for storing the address values is required while a buffer structure is managed by a WSP(Write Start Pointer) and a TSP(Transmit Start Pointer) which are 2 logical addresses.
