Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This Standard supersedes CAN/CSA-ISO/IEC 20060-04 (adoption of ISO/IEC 20060:2001, first edition, 2001-11-01).
At the time of publication, ISO/IEC 20060:2010 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC.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.
