Programmable high performance data communication adapter for high speed packet transmission networks

摘要

A high performance data packet buffering method and a programmable data communication adapter for high speed packet transmission networks are disclosed. The line adapter includes programmable processing means, for receiving and transmitting data packets of fixed or variable length. This system is characterized in that it comprises· means for buffering (132) said data packets,· means for identifying said buffering means and said data packets in said buffering means,· means for queueing (Figure 15) in storing means (131) said identifying means in a single instruction,· means for dequeueing (Figure 16) from said storing (131) means said identifying means in another single instruction ,· means for releasing said buffering means,    Each instruction comprises up to three operations executed in parallel by said processing means :· an arithmetical and logical (ALU) operation on said identifying means,· a memory operation on said storing means, and· a sequence operation.
