DS DS/ISO/IEC 20060: Information technology - Open Terminal Architecture (OTA) - Virtual machine
SDO: DS: Dansk Standard
DOD Adopted ANSI Approved Approved
This International Standard provides the specifications for the standard Open Terminal Architecture (OTA) kernel in several layers: . definition of the virtual machine (VM); . description of the services provided by the VM to terminal programmers; . specification of a set of tokens representing the native machine language of the VM; . specification of the format in which token modules are delivered to an OTA kernel for processing. OTA defines a standard software kernel whose functions and programming interface are common across all terminal types. This kernel is based on a standard "virtual machine," which is implemented on each CPU type and which provides drivers for the terminal's I/O and all low-level CPU-specific logical and arithmetic functions. High-level libraries, terminal programs and payment applications may be developed using these standard kernel functions.
