Logic chip and board card device with same

Abstract

The invention discloses a logic chip and a board card device with the same. The logic chip comprises a serial port console module and a state control register. The serial port console module is used for receiving the read-write information which is from user equipment and used for reading and writing the state control register. The serial port console module is used for performing read-write processing on the state control register according to the read-write information, acquiring the corresponding read-write processing result of the state control register, and feeding back the processing result to the user equipment. The logic chip has the advantages that by the serial port console module added inside the logic chip, read and write of the state control register can be performed through the serial port console module, dependency between the function debugging of the logic chip and the debugging of a processor is avoided, and debugging efficiency is increased. By the arrangement, the idle resources of programmable logic can be utilized, and no extra chips are needed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a reading logic chip and a board device containing the logic chip. Background technique [0002] There is a logic chip in the complex digital circuit board, which is used to cooperate with the BMC (Board Management Controller, board management controller) to realize the management and control of the key signals of the board and realize the auxiliary functions required for the operation of the board. The logic chip is implemented by CPLD (Complex Programmable Logic Device) or FPGA (Field Programmable Gate Array, Field Programmable Gate Array). The functions of the logic chip include: generating system reset timing, and distributing reset and interrupt signals. Realize the configuration or management of processors or other functional chips and modules. Realize local interface conversion, multi-channel selection, and bus allocation functions. Realize functions such as power ...

AI Technical Summary

Problems solved by technology

[0005] Due to the dependency between the function debugging of the logic chip and the debugging of the processor, the debugging process needs to be carried out sequentially, and the efficiency is low

Since the logic chip has an important influence on the reset signal of the processor, it may cause an abnormal reset of the processor during the debugging process, causing the debugging process to be interrupted unexpectedly
