A Multiport Buffer Memory for an Internet Packet Voice/Data Gateway

摘要

The internet packet voice/data gateway is for an experimental wideband satellite network. The gateway consists of a central processor and a number of microprocessor-controlled interfaces to local networks at each site and to the satellite network. The Multiport Buffer Memory is accessible from any of these microprocessors, and increases system throughput by allowing the bulk of the packet traffic between the networks to pass through it without having to pass through the central processor. The shared memory consists of a main memory organized as 64K words x 16 bits and an auxiliary pointer memory of 4K words x 16 bits. The Multiport Buffer Memory complex includes an automated intelligent memory management strategy which makes the memory resource allocation transparent to the microprocessor-based systems which share the memory.
