Problems solved by technology

As the number of single boards increases, the value of n will increase, resulting in a further increase in the number of signal lines
These signal lines will take up a lot of PCB (Printed Circuit Board, printed circuit board) space on the motherboard and backplane, and waste the logic resources of the CPLD
Moreover, in order to deploy a large number of signal lines between the main board and the backplane, the number of connectors needs to be increased. The use of these connectors will further occupy PCB space and increase the risk

Abstract

The present invention provides a hardware control circuit and a control method thereof. The hardware control circuit includes: a processor, a CPLD, a backplane, and a plurality of single boards; the single board includes a parallel-to-serial conversion module, and the CPLD includes a serial-to-parallel conversion module and a codec module. ; The parallel-to-serial conversion module is used to obtain the hardware information of the single board, and sends the hardware information to the backplane in a serial manner through the data signal line between the single board and the backplane; The data signal line corresponding to the single board between the board and the CPLD obtains hardware information from the backplane in a serial manner, and stores the hardware information in the data register corresponding to the single board; The hardware information of the single board is acquired in the corresponding data register, and the hardware information of the single board is output to the processor. Through the technical solution of the invention, the number of signal lines between the backplane and the single board is reduced, the number of signal lines between the backplane and CPLD is reduced, and the PCB wiring space of the mainboard and the backplane is saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a hardware control circuit and a control method thereof. Background technique [0002] like figure 1 As shown in FIG. 2 , it is a schematic structural diagram of the storage system. The backplane includes multiple slots, and a single board can be inserted into the backplane. As the processing capability of the storage system increases, more and more boards are inserted into the backplane. In order to enable the CPU (Central Processing Unit, central processing unit) to distinguish each board, it is necessary to report the hardware information of the board to the CPU. The hardware information is indicated by high and low levels, that is, the hardware information can be M-bit high and low levels , For example, when M is 16 bits, the high and low level 1111111011001000 indicates a hardware information, and the high and low level 0111011001000000 indicates another hardware in...
