Title:
デュアルポートメモリエミュレーション方式によるスイッチファブリック
Document Type and Number:
Japanese Patent JP2004536515
Kind Code:
A
Abstract:
A switch fabric supporting a dual port memory emulation scheme using two single port memories. If a read action for retrieving a stored packet is scheduled for one single port memory, the write action for storing a packet is performed on the other single port memory. Each packet is stored in the memory a data word at a time, and referenced by a linked list of previous pointers that refer to a previous data word stored in the memory, resulting in a single write-in step of the pointer information for each data word. In retrieving the stored packet, each data word is retrieved in a backward manner by following the linked list of previous pointers where the end of the packet is retrieved first, and the beginning of the packet is retrieved last.
