Abstract
A mechanism that enables allocation and recovery of buffer resources in both burst access and single access modes of operation is presented.
Claims32
An apparatus comprising:
- a processing device coupled to a memory that stores addresses of memory resources in a ring structure of entries;
- and
- logic, coupled to the processing device and the memory, usable by the processing device to access entries in bursts and singly.
A method comprising:
- providing a first pointer and a second pointer for separately indexing into a ring structure of indexed entries corresponding to addresses of memory resources;
- using the first pointer to access entries in bursts;
- and
- using the second pointer to access entries singly.

A system, comprising:
- at least one physical layer device;
- at least one Ethernet medium access control device coupled to the at least one physical layer device;
- at least one processor to process packet data received via the at least one physical layer device and the at least one medium access control device;
- memory;
- and
- logic coupled to the processing device and the memory, usable by the at least one processor to access entries in bursts and singly.
