Real-Time Java: An Introduction - O'Reilly Media
Direct memory access. Java RTS allows direct access to physical memory, making it similar to J2ME. No surprise there: one of the main target platforms of real-time Java is embedded systems. This means that now you can create device drivers written in pure Java. Although memory access is not directly a real-time issue, physical memory access is desirable for many applications. Java RTS defines a new class that allows programmers byte-level access to physical memory, as well as a class that allows the construction of objects in physical memory. One might think that physical memory access is the point where Java gives up its main principles--reliability and safety--and takes a step back towards C, but this isn't the case. Java maintains strong security protections by controlling memory bounds and data contents. Read full article from Real-Time Java: An Introduction - O'Reilly Media
