Design method of repeater chip

Abstract

The present invention provides a method for designing a repeater chip. In this method, through design, the repeater chip can implement interconnection between nodes, and functions of collecting, classifying, storing, forwarding, sorting, and sending packet sequences of the repeater chip are implemented, thereby implementing effective extension of a high-speed transmission link between nodes and reducing hardware design complexity and a design risk. The structure of the repeater chip is formed of an interface detection unit, a sequence storing unit, a sequence forwarding unit, a sequence determining unit, and a sequence sorting unit. Through the design, integration of a multi-path processor or that of a multi-node interconnected system is implemented, high-complexity hardware cabling is effectively implemented, and the design complexity of interconnection and cabling and the design risk in a multi-path CPU system are effectively reduced; the repeater chip has a high application value in a multi-node interconnected system in which it is difficult to lay out a PCB, which can effectively extend the cabling length between the interconnected nodes and meets the cabling rule requirement, thereby greatly reducing the complexity of hardware cabling, the PCB design complexity and the design risk.

Description

technical field [0001] The invention relates to the fields of high-end server design and large-scale integrated circuit design, in particular to a design method of a repeater chip. Background technique [0002] With the rapid development of computer technology and integrated circuit technology, in order to meet the needs of economic and social development, multi-channel computer systems or multi-node interconnection systems have become one of the bottlenecks restricting the key areas of social development. Information fields such as huge data calculation and data analysis, complex graph analysis and scientific budgeting have extremely high requirements on the performance of computer systems. Therefore, it is necessary to build a huge multi-channel computer system in order to better adapt to the application requirements in various fields today, but on the other hand, it is also caught in the technical difficulties of interconnecting multi-channel computer systems.

Therefore, it is necessary to build a huge multi-channel computer system in order to better adapt to the application requirements in various fields today, but on the other hand, it is also caught in the technical difficulties of interconnecting multi-channel computer systems. The limited PCB area is multi-channel or multi-node interconnection. The design of the interconnection system brings difficulties. At the same time, the high-speed interconnection system also design specifications for the transmission length of the link, which further increases the difficulty of the design of the node interconnection system.
