Information technology - Open terminal architecture (OTA) - Virtual machine (Adopted ISO/IEC 20060:2010, second edition, 2010-07-01)
Scope

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
