CDMA (code division multiple access) on-chip network architecture based on standard orthonormal basis and realization method of CDMA on-chip network architecture

Abstract

The invention discloses a CDMA (code division multiple access) on-chip network architecture based on a standard orthonormal basis and a realization method of the CDMA on-chip network architecture. The CDMA on-chip network architecture and the method mainly solve the problem that in the prior art, the on-chip network architecture cannot reduce the resource waste or reduce the power consumption while ensuring the transmission quality and the transmission efficiency. The CDMA on-chip network architecture based on the standard orthonormal basis comprises a network transmitting module, an arbitration module and more than two processing units, wherein the network transmitting module and the arbitration module are integrated, and the processing units are connected with the network transmitting module and the arbitration module respectively through network nodes. Through the scheme, the CDMA on-chip network architecture and the method have the advantages that the goals that the transmission quality and the transmission efficiency are high, in addition, the resource waste and the power consumption are low are reached, and high practical value and popularization value are realized.

Description

technical field [0001] The invention relates to a CDMA on-chip network architecture based on orthonormal basis and its realization method. Background technique [0002] As the number of processors integrated on a single chip increases, multiprocessor systems have increasingly used Network-on-Chip (NoC) architectures to solve the problems of large inter-processor communication and high communication delay. [0003] The existing network-on-chip architecture mainly includes the traditional network-on-chip architecture based on the cache method. This network-on-chip architecture can solve the problem of data communication between nodes and can improve a certain data transmission delay, but it is not suitable for the connection between two nodes. However, the stability of the data transmission delay cannot be guaranteed, that is, the transmission delay between nodes is a variable and is affected by the network congestion situation. Therefore, the buffer-based network-on-chip is ...
