Embodiment Construction

[0080] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0081] Such as figure 2 As shown, the multi-chip serial communication system of the present invention includes a control chip and multiple (for example, at least two) arithmetic chips. Among them, each arithmetic chip has a downlink data receiving end RXDI, a downlink data sending end RXDO, an uplink data receiving end TXDI, an uplink data sending end TXDO, a flow control receiving end CTSI, and a flow control sending end CTSO.

[0082] In each computing chip, its downstream data receiving terminal RXDI is connected to the downstream data sending terminal RXDO of the previous stage (one level closer to the control chip), and its downstream data sending terminal RXDO is connected to the next stage (further away The first level of the control chip) t...

Abstract

The invention discloses a multi-chip serial communication system. The multi-chip serial communication system is a multistage operation chip serial communication structure formed through connecting downlink data reception ends, downlink data transmission ends, uplink data reception ends, uplink data transmission ends, flow control reception ends and flow control transmission ends of a plurality ofoperation chips; and a control chip is connected with the 0-stage operation chip to form a serial communication system structure. Transmission of uplink data of the operation chips is coordinated through flow control signals of the flow control reception ends and the flow control transmission ends by utilizing designed downlink and uplink communication protocols. The system provided by the invention is low in line structure design difficulty, so that the production cost is lower; by means of uplink and downlink serial communication protocols, mutual interference between the uplink and downlinkcommunication data of each operation chip is eliminated, so that each operation chip and correctly receive and transmit the data; and meanwhile, two manners of broadcast and unicast are supported, sothat both efficiency and flexibility are considered.

Description

Technical field [0001] The invention relates to the field of chip wiring communication, in particular to a multi-chip serial communication system. Background technique [0002] A complex computing system with a huge amount of computing is often composed of a control chip and many computing chips, such as figure 1 As shown, in this system, the control chip is responsible for configuring computing chips and distributing computing tasks to each computing chip. Each computing chip is responsible for processing computing data and returning computing results to the control chip. It should be noted, figure 1 It is only an example, which does not include the connection relationship between the various computing chips and the connection relationship with the control chip, where the number of computing chips only represents multiple, and does not have the effect of limiting the number of computing chips. [0003] As the performance requirements of the computing system become higher and highe...
