Problems solved by technology

[0010] The disadvantage of the above technical solution is that when the interrupt is connected to the PCI interrupt INTA#, INTB#, INTC#, INTD#, hardware engineers and BIOS engineers are required to re-modify the circuit and register resource allocation according to the chipset and peripheral configuration. , the hot-swap service program should also be modified accordingly, the design is complex and not reusable, and it is not conducive to modularization

Abstract

The invention provides a processing method capable of achieving hot plug of a PCI (Peripheral Component Interconnect) product, and comprises the following steps: (a) a CPLD (Complex Programmable Logic Device) module is provided, and is simulated to a slave unit requesting serial interrupt, and is hung on an interrupt line requesting serial interrupt of a south bridge chip of a main control card; (b) after the CPLD module receives an enumeration signal transmitted from a hot pluggable card, the enumeration signal is converted into a time sequence requesting serial interrupt to form interruption for the south bridge. The invention has the advantages that the designed CPLD is used for solving the problem of the hot plug of the compact PCI product so as to simplify the design, the debugging and the maintenance of a program and the like, improve the reusability of the product, shorten the development cycle of the product, improve the quality of the product, and save the design cost.

Description

technical field [0001] The invention relates to the field of compact PCI products, in particular to a processing method and system capable of realizing hot plugging of compact PCI products. Background technique [0002] Compact PCI products are composed of a compact PCI main control card, a backplane and peripheral cards. When the peripheral cards are inserted into or pulled out of the backplane, the main control card is responsible for monitoring. The common hot-swappable function of compact PCI products can be realized by hot-swappable peripheral cards and compact PCI main control cards. The following is a brief introduction. [0003] The schematic diagram of the logical relationship between the peripheral card of Compact PCI (Compact PCI: Compact PCI) and the backplane of Compact PCI is as follows: figure 1 As shown, it includes a compact PCI backplane 10 and a hot-swappable peripheral card 19, which further includes a hot-swappable controller 191, a hot-swappable bridge...
