Data processing device and method for interconnecting circuits

Abstract

Provided are a data processing apparatus and method for an interconnection circuit, which relate to an interconnection node used for connecting one or more transaction data sources to one or more transaction data destinations in an interconnection circuit. The data processing apparatus comprises: at least one input end and at least one output end, the input end including a plurality of input ports, an output port, at least two multiplexers and at least one buffer memory; a buffer storage distribution circuit, which controls the multiplexers to distribute a temporary storage location for input transaction data according to a current state of the buffer memory; a routing selection circuit, which selects an output end for the transaction data of a buffer queue; an arbitration circuit, which arbitrates the buffer queue having a transmission priority and enables multiple transaction data transmission contending for the same output end to successively obtain the output path occupation right according to a pre-set arbitration policy; and a multi-path selector circuit, which is connected to the output port and the output end, and transfers data transmission in the interconnection circuit.

Description

technical field [0001] The invention belongs to the field of integrated circuits. More particularly, the present invention relates to a data processing apparatus and method as an interconnection node in said interconnection circuit for connecting one or more transactional data sources to one or more transactional data destinations. Background technique [0002] There are often data transmissions between one or more transaction data sources and one or more transaction data destinations in integrated circuits. Such circuits often do not simply connect the source and destination directly through a data link, but need to pass through One or more converging nodes converge and distribute transaction data, and all source and destination nodes are connected to each converging node to form an interconnection circuit, and the converging node in the interconnection circuit is a data processing device for receiving The data from the thing data source is forwarded to the next converging...

Problems solved by technology

However, although this patent document can provide forecast data generation, forecast data storage and forecast data evaluation at the converged interconnection node, which improves the data processing efficiency to a certain extent, it needs to reserve space for the forecast data, and the input buffer In terms of settings, it is necessary to set a separate buffer for each output port, which has the problems of wasting storage space and high power consumption
