PROGRAMMABLE HIGH PERFORMANCE DATA COMMUNICATION ADAPTER FOR HIGH SPEED PAQUET 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 receivin g 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.
