Implementation mode of PISA manager under Linux system

Abstract

The invention discloses an implementation mode of a PISA manager under an Linux system, which is applied to a creative infrastructure system architecture based on an information technology application innovation platform. The PISA manager is used for managing an API (Application Program Interface) layer to call an SPI (Serial Peripheral Interface) layer in a cross-process manner and comprises service handle management, service request ID (Identity) management, memory management, synchronous call implementation and asynchronous call implementation management; each API layer calls an SPI layer to generate a unique service handle of the system; each time the API calls the SPI layer, a unique service request ID of the system is generated; and through a file mapping shared memory and a cross-process lock, the service handle and the service request ID generated by the PISA manager, and the calling process number and the calling process handle of the API layer are stored. According to the invention, the equipment service of multi-process access financial self-service equipment can be supported.

Description

technical field [0001] The invention belongs to the technical field of financial self-service equipment, and in particular relates to an implementation method of a PISA manager under a Linux system. Background technique [0002] At present, most financial terminal equipment, such as self-service equipment, etc., follow the CEN / XFS (The European Committee for Standardization / Extensions for Financial Services) specification based on the Windows operating system. The extension specification is closely related to the Windows system and has a strong operating system binding feature, so it cannot be directly migrated to other systems. [0003] As the Linux system is gradually applied to more and more fields, there have been XFS implementation methods based on the Linux system. Most of the implementations use the method of direct calling, but this method causes the device to not support multi-process access. Moreover, device services are strongly coupled with applications.

[0002] At present, most financial terminal equipment, such as self-service equipment, follow the CEN / XFS (The European Committee for Standardization / Extensions for Financial Services) specification based on the Windows operating system. The CEN / XFS specification is a financial service standard formulated by the European Standardization Committee The extended specification is closely related to the Windows system and has a strong operating system binding feature, which cannot be directly migrated to other systems

[0003] As the Linux system is gradually applied to more and more fields, there have been XFS implementation methods based on the Linux system. Most of the implementations use the method of direct calling, but this method causes the device to not support multi-process access. Moreover, device services are strongly coupled with applications.
