Device for dispatching and arbitration

Abstract

This invention discloses one device to adjust and arbitrate, which comprises the following parts: time lag generation module, arbitrate time unit generation module, input data responding module and output data responding module, wherein, the said arbitrate time unit generation module is to control it generate effective label speed by meter circuit; the said time lag generator module is to receive label for energy signal for meter operation composed of meter circuit; the input data responding module is to receive time piece effective signal to test current terminal is effective.

Description

technical field [0001] The invention relates to a scheduling and arbitration device used in the design process of integrated circuits. Background technique [0002] In the design process of digital chips, arbitrators and schedulers are often used to realize the sharing of hardware resources, multiplexing and demultiplexing of data streams, etc. Commonly used arbitration structures include priority-based arbitration, round_robin, weighted arbitration, etc. When designing these arbitrators, the common method is to use a state machine to control the current priority, and then use an arbitration circuit, which is based on the state machine The priority saved in and the current arbitration and scheduling request send out corresponding response signals. [0003] With the development of communication technology, the capacity of switches is getting bigger and bigger, and the types of services supported by switches are getting more and more. At the same time, the integration of chip...

Problems solved by technology

[0004] That is to say, when the traditional arbitration and scheduling device processes multi-service and large-flow data, the consumption of hardware resources is relatively large, resulting in relatively high chip area and power consumption.
