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

Abstract

The invention provides a data processing apparatus and method for an interconnection circuit. The data processing apparatus is an interconnection node used for connecting one or more transaction data sources to one or more transaction data destinations in the interconnection circuit. The data processing apparatus comprises at least one input end, at least one output end, a buffer storage distribution circuit, a route selection circuit, an arbitration circuit and a multiplexer circuit, wherein the input ends include a plurality of input ports, output ports, at least two multiplexers and at least one buffer memory; the buffer storage distribution circuit controls the multiplexers to allocate temporary storage positions to input transaction data according to current states of the buffer memories; the route selection circuit selects the output ends for transaction data of a buffer queue; the arbitration circuit arbitrates the buffer queue with a priority transmission right and enables transmission of multiple transaction data competing the same output end to obtain output access occupation rights in sequence according to a preset arbitration policy; and the multiplexer circuit is connected with the output ports and the output ends, 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...
