Abstract
A system and method for maintaining information of pending operations are described. A buffer uses multiple linked lists implementing a single logical queue for a single requestor. The buffer maintains multiple head pointers and multiple tail pointers for the single requestor. Data entries of the single logical queue are stored in an alternating pattern among the multiple linked lists. During the allocation of buffer entries, the tail pointers are selected in the same alternating manner, and during the deallocation of buffer entries, the multiple head pointers are selected in the same manner.
