چکیده
Keywords: real-time Java, real-time scheduling, embedded systems, real-time kernel and operating system, multithreading This paper presents a real-time Java hardware and software system for use in embedded applications. The system includes a multithreaded Java microcontroller, an adapted Java Virtual Machine (JVM) and an extended Application Programming Interface (API). The microcontroller core is designed with a multithreaded pipeline and hardware support for real-time scheduling algorithms. The Java Virtual Machine consists of trap routines for complex Java byte-codes, a real-time garbage collection and a class loader for creating real-time data structures. On a higher level, the Application Programming Interface provides easy real-time thread management and access to hardware components like serial interfaces and timer/counter units.
