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 comprisesPPmeans for buffering (132) said data packets, PPmeans for identifying said buffering means and said data packets in said buffering means,PPmeans for queueing (FIG. 15) in storing means (131) said identifying means in a single instruction,PP means for dequeueing (FIG. 16) from said storing (131) means said identifying means in another single instruction, PPmeans for releasing said buffering means,P PEach instruction comprises up to three operations executed in parallel by said processing means:PPan arithmetical and logical (ALU) operation on said identifying means,PP memory operation on said storing means, andPPa sequence operation.
