Document Type and Number:
WIPO Patent Application WO/2023/006006
Kind Code:
A1
Abstract:
A roller arbitration method for on-chip data exchange. On the basis of an N×N cross network of N input ports and N output ports, the method comprises the following steps: S1, determining a priority arbitration arrangement; S2, determining whether each expected transmission pair in the arrangement has a transmission requirement; if yes, determining that the expected transmission pair is an actual transmission pair, and immediately performing data transmission on the determined actual transmission pair; if not, considering that the expected transmission pair is a non-transmission pair; S3, performing sequential row/column or column/row arbitration, and selecting switching points having a high priority as an actual transmission pair; S4, after the polling is completed in step S3, scrolling the priority arbitration arrangement to obtain a new arbitration arrangement; and S5, cyclically performing S2-S4.
