Abstract

The invention is a kind of multi-processor system and the method for sharing guiding model, which refers to multi-CPU system with PCI controller in communication field. The system includes several processors, each processor has matched control state register, dynamic RAM, static RAM, series port, the processors are connected together through PCI bus, and uses a PCI arbiter, one processor with the guiding model is uses as the primary processor, the other processors are used as slave processors. When powdered on, the primary CPU takes instruction form itself guiding model, and the slave processor acquires instruction from RAM, the primary CPU resets the slave CPUs after initializing them, now, it can run. The invention is simple; it can save the guiding model, and the Ethernet controller.

Description

technical field

[0001] The present invention relates to a kind of multiprocessor (CPU) system and the method for multi-CPU system sharing BOOT FLASH (guide module), relate in particular to the multi-CPU system and The method for multiple CPUs to share the boot module in the system. Background technique

[0002] At present, in order to increase the processing capacity and integration of single boards in embedded systems, multiple sets of CPU systems are often designed on the same single board. Each system comes with a BOOT FLASH, and often uses PCI controllers. CPLD (Complex Programmable Logic Device, Complex Programmable Logic Device) designs a PCI arbiter by itself, and downloads the version file from the network port or FLASH. Such as figure 1 and image 3 shown. figure 1 It is a hardware principle block diagram of a multi-CPU system designed according to the prior art method. In the system, two or more sets of CPU systems each have a BOOT FLASH, a PCI arbiter, and at ...
