object synchronization). Java threads native threads aJile processor, extended bytecode instructions used implement these Java threading primitives (sleep, wait, notify, notifyall, yield, monitor enter, monitor exit, interrupt) order provide extremely fast atomic (noninterruptible) executive operations. on-chip real-time thread manager performs priority-based preemptive scheduling with extremely fast context switch times less than 1µs. addition, aJile Multiple (MJM) technology enables multiple applications execute concurrently independently deterministic, timesliced scheduling. Each employs threading memory policies enable real-time applications execute concurrently with networked applications without threat garbage collection (G.C.) pauses other interruptions. capability takes Java "sandbox" security model next level, providing mechanism easily isolate applications allocated resources. aJile RTOS enables hard real-time applications independently safely co-exist with networked applications. Development Tools development environment allows off-the-shelf that produces Java standard class files such Eclipse Netbeans. consists following components: Optimizing Linker/Application Builder (JEMBuilder) Application Debugging Tools Multimedia Evaluation aJ-200MEK board JTAG-to-USB converter cable power adapter Schematics gerber file downloaded aJile website www.ajile.com
