Service-Guaranteed Multi-Port PacketMemory for Parallel Protocol Processing Architecture

• Parallel processing architectures have been increasingly utilized due to their potential for improving performance and energy efficiency. Unfortunately, the anticipated improvement often suffers from a limitation caused by memory access latency and latency variation, which consequently impact Quality of Service (QoS). This paper presents a service-guaranteed multi-port packet memory system to boost parallelism in protocol processing architectures. In this proposed memory system, all arriving packets are guaranteed a memory space, such that, a packet memory space can be allocated in a bounded number of cycles and each of its locations is accessible in a single cycle. We consider a real-time Voice Over Internet Protocol (VOIP) call as a case-study to evaluate our service-guaranteed memory system.
