信息技术.开放终端结构(OTA)规范.虚拟机

[中文适用范围]： 本标准规定了开放终端架构（OTA）内核在多个层次上的规范： - 虚拟机的定义； - 虚拟机向终端程序员提供的服务描述； - 代表虚拟机本机语言的一组标记的规范； - 标记模块交付给OTA内核进行处理的格式规范。 OTA定义了一个标准软件内核，其功能和编程接口在所有终端类型中都是通用的。该内核基于一个标准的"虚拟机"，该虚拟机在每个CPU类型上实现，并为终端的I/O以及所有低层CPU特定的逻辑和算术功能提供驱动程序。高级库、终端程序和支付应用程序可以使用这些标准内核功能进行开发。 [外文原描述]： ISO/IEC 20060:2010 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 VM, 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.
