Java实时规范RTSJ到底是什么?

问题描述

Java实时规范到底是什么?也就是说，它与常规" Java SE或Java EE规范有何不同?

What exactly is the Java Real Time Specification? That is, how does it differ from the "regular" Java SE or Java EE specifications?

推荐答案

基本上，这是常规VM(以及它的俗套GC)无法实现的，因此需要其他规范:

Basically, this is something you won't be able to achieve with the regular VM (and its stop-the-world GC amongst other things), hence the need for another specification:

RTSJ旨在无缝地 扩展任何Java系列-是否 Java平台标准版(Java SE); Java平台，微型版 (Java ME);或Java平台， 企业版(Java EE)-和 要求任何 实现同时通过JSR 1 技术兼容性套件(TCK)和 平台的TCK-Java SE， Java ME或Java EE-它在其上

The RTSJ is designed to seamlessly extend any Java family -- whether the Java Platform, Standard Edition (Java SE); Java Platform, Micro Edition (Java ME); or Java Platform, Enterprise Edition (Java EE) -- and has the requirement that any implementation pass both the JSR 1 technology compatibility kit (TCK) and the TCK of the platform -- Java SE, Java ME, or Java EE -- on which it is based.

RTSJ引入了几个新的 支持实时功能 操作.这些功能包括新功能 线程类型，新的内存管理 型号等新推出 构架. (...)

The RTSJ introduces several new features to support real-time operations. These features include new thread types, new memory-management models, and other newly introduced frameworks. (...)
