Abstract

The invention discloses a sequential control method for different partitions of a server system based on nios II, which is specifically implemented as follows: through an Avalon bus, the control on circuits such as a peripheral sequential module, an I2C bus module, a SDRAM module and an off-chip flash memory module is realized; a partition mode detection module is used for detecting the partition mode of the system in real time and then sending a partition mode signal to a CPU module; the CPU module is used for generating a control signal according to the partition mode, sending the control signal to the sequential module, carrying out communication with a management circuit by the I2C module, and feeding back the partition mode and sequential information; and the sequential module is used for carrying out selection on different sub-sequential modules according to the control signal sent by the CPU module. Compared with the prior art, the sequential control method for different partitions of a server system based on nios II can automatically detect partition modes and carry out corresponding sequential control, and implements the sequential control mode of Multi-PCH, thereby providing a flexible way for multiple paths of partition configurations.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a timing control method for different partitions of a nios II-based server system with strong practicability. Background technique [0002] Ordinary server systems generally have a fixed partition mode during use, which leads to inability to perform flexible partition configuration during work, and the single PCH working mode cannot better provide redundancy. For multi-channel server systems, it has become a development trend to flexibly configure different partition modes according to requirements. [0003] In different partition configuration modes and multi-PCH working modes, the working timing of the server system is different. Based on this, a timing control method for different partitions of the server system based on nios II is now provided. Contents of the invention [0004] The technical task of the present invention is to provide a highly practical timing co...
