Abstract

The invention discloses an interrupt processing system and method applied to PCIE to heterogeneous equipment. The interrupt processing system comprises a PCIE adapter card, a storage unit and a processing unit. Wherein the PCIE riser card is provided with a control unit, identification information and at least one communication interface, and the control unit is electrically connected to the communication interfaces; wherein the storage unit is provided with a service program, a drive program and a plurality of cache structures, and each cache structure is used for storing interrupt requirements; the processing unit is electrically connected to the PCIE riser card and the storage unit, the processing unit executes a driving program and a service program, the driving program establishes a plurality of transmission channels according to the identification information, the driving program assigns corresponding communication interfaces to different transmission channels, and the transmission channels are used for transmitting interrupt requirements or access requirements; and if the drive program detects the transmission interruption requirement of any transmission channel, the drive program stores the interruption requirement into the cache structure, and if the interruption requirement exists in the cache structure, the service program processes the interruption requirement.

Description

technical field [0001] A system and method for interrupt processing of peripheral hardware resources, especially related to the interrupt processing system and method applied to PCIE for heterogeneous devices Background technique [0002] Although various low-speed communication interfaces (for example: Digital I / O, Analog I / O or RS-232, etc.) that are traditionally used can be transferred to other high-speed communication interfaces (for example: Universal Serial Bus (Universal SerialBus, USB) or Peripheral Component Interconnect Express (PCIE for short). However, the Interrupt Service Routine (ISR) that is limited by the traditional communication interface will affect the transmission efficiency of the high-speed transmission interface. [0003] Because the traditional communication adopts the polling mechanism, the controller will ask the connected terminal equipment one by one whether there is an interrupt request. When a terminal device sends an interrupt request, the...
