Multi-chip arithmetic device, virtual currency mining machine and computer server

Abstract

The invention discloses a multi-chip arithmetic device, a virtual currency mining machine and a computer server. The multi-chip arithmetic device comprises a plurality of chips which are disposed on aPCB; and each chip comprises at least one mode selection signal pin which is used for controlling functions of the chip pins, so that the chip pins are at least switched between an input function andan output function. At least one mode selection signal pin is arranged for each chip, and the functions of the chip pins can be changed according to different mode selections, and adjacent or similarchips can be connected nearby, so the problems of signal interference and the like caused by wiring intersection and line extension are avoided, the connection among the plurality of chips is facilitated, the interconnection difficulty of the PCB can be reduced, and the board-level cost is reduced.

Description

[0001] This invention is a divisional application of the Chinese invention patent application with the application number 201810853973.8, the application date is July 30, 2018, and the invention name is "multi-chip single-layer board computing device, virtual currency mining machine and computer server". technical field [0002] The invention relates to the field of integrated circuits, in particular to a multi-chip computing device and a manufacturing method thereof, a virtual currency mining machine and a computer server. Background technique [0003] In a computing board composed of multiple chips, there are many interconnected signals between the chips, which often put a lot of pressure on the board-level wiring, which may increase the area of ​​the PCB or require more layers to meet the wiring requirements. need. In a system that is sensitive to area and cost, the size of the PCB board and the number of layers of the board will be limited, which will bring great difficu...

AI Technical Summary

Problems solved by technology

[0003] In a computing board composed of multiple chips, there are many interconnected signals between the chips, which often put a lot of pressure on the board-level wiring, which may increase the area of ​​the PCB or require more layers to meet the wiring requirements. need

In a system that is sensitive to area and cost, the size of the PCB board and the number of layers of the board will be limited, which will bring great difficulties to wiring

[0004] In the prior art, the position of the PIN pin of a single chip is fixed. When multi-chip board-level interconnection is limited to the width of the board, the interconnection of communication signals will become difficult. For a single-layer PCB board (i.e. communication signal wiring Single-layer setup), if there is crossover between signals, board-level signal routing will become extremely difficult, and it is easy to interfere with each other
