Array channel control system, method, controller, storage medium and application

Abstract

The invention belongs to the technical field of network exchange data transmission, and discloses an array channel control system, method, controller, storage medium and application. The channel control module is used to generate the FlashChip self-defined underlying commands required by the NandFlash interface controller, and NandFlash The cache and data management mechanism required for data interaction are also included, controlling four physical channels; NANDFLASH interface control is used to realize the underlying NandFlash physical interface operation, and realize the interaction timing with the physical interface of NandFlashChip. The invention uses 32bit storage units to work concurrently, solves the problem of insufficient data throughput in the NANDFLASH asynchronous mode, and makes the data throughput of the NANDFLASH interface on the switch side reach 3Gbps, which can fully meet the data storage requirements of the on-board switch.

Description

technical field [0001] The invention belongs to the technical field of network switching data transmission, and in particular relates to an array channel control system, method, controller, storage medium and application. Background technique [0002] At present, in the cosmic space, the network exchange data transmission between stars and stars or between stars and earth will be affected by many interference factors, and the phenomenon of network disconnection is prone to occur, that is, data packets will be in the DTN (Delay Tolerant Network). This can improve the success rate of packet transmission by storing the packet and sending it after the two nodes have established an end-to-end path. On the other hand, the satellite cannot be kept within the observation range of the satellite observation station all the time, so the data that needs to be sent to the ground through the feeder circuit may not be transmitted in time and need to be temporarily stored in the on-board ex...

AI Technical Summary

Problems solved by technology

[0007] (1) The prior art uses the synchronous mode of NAND FLASH, adopts upper and lower edge sampling (DDR) to improve the transmission throughput of the NAND FLASH interface, and uses an asynchronous mode in the aerospace satellite system, causing if the 8bit data bus continues to be used to make the NAND FLASH data interface throughput lower

[0008] (2) In the storage operation of the prior art, for the NAND FLASH storage required by the on-board switching system, the CPU cannot be used to distribute data and issue commands to the controller

Nevertheless, there are still considerable difficulties in bad block management, power-on self-recovery and storage address allocation based on pure hardware
