INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING SYSTEM, AND COMMUNICATION DEVICE

摘要

An information processing device includes a transfer unit and an interface unit, the interface unit distributes transmission to a plurality of first lanes, and generate reception information from a plurality of pieces of distribution reception data received through a plurality of second lanes, the transfer unit includes a reception processing unit to extract reception data included in the reception information, and first error information indicating an error in any of the first lanes and a degeneration management unit to generate first degeneration information indicating a use stop lane among the first lanes, based on the first error information, generate second degeneration information indicating a use stop lane among the plurality of second lanes, based on second error information that is output from the interface unit, and cause the transmission processing unit to generate transmission information including the second degeneration information.

主权项

1. An information processing device comprising:
an arithmetic processing device; a storage device configured to store data processed by the arithmetic processing device; and a communication device, wherein the communication device includes a transfer unit configured to output transmission information including transmission data which is output from the arithmetic processing device, and output reception data included in reception information to the arithmetic processing device; and an interface unit configured to distribute the transmission information into a plurality of pieces of distribution transmission data, transmit the distribution transmission data to a plurality of first lanes, respectively, and generate reception information from a plurality of pieces of distribution reception data that are respectively received through a plurality of second lanes, wherein the transfer unit includes a transmission processing unit configured to generate the transmission information; a reception processing unit configured to extract reception data included in the reception information, and first error information indicating an error in any of the plurality of first lanes included in the reception information; and a degeneration management unit configured to generate first degeneration information indicating a use stop lane for which use is stopped, among the plurality of first lanes, based on the first error information, generate second degeneration information indicating a use stop lane for which use is stopped, among the plurality of second lanes, based on second error information that is output from the interface unit, and cause the transmission processing unit to generate transmission information including the second degeneration information, and wherein the interface unit includes a transmission unit configured to transmit distribution transmission data corresponding to the transmission information to lanes excluding the use stop lane indicated by the first degeneration information, among the plurality of first lanes; a reception unit configured to generate the reception information from distribution reception data that is received through lanes excluding the use stop lane indicated by the second degeneration information, among the plurality of second lanes; and a detection unit configured to detect an error in any of the plurality of pieces of distribution reception data, and generate the second error information indicating a second lane through which error-detected distribution reception data is transmitted.
