Course Description:

'' the developing real-time applications for the java platform course provides students with the essential skills required to use the real-time capabilities of the real-time specification for java (rtsj) toreal-time applications.



who can benefit

students who can benefit from this course are programmers, developers, and software architects who will be involved in development of real-time systems using the java programming language with the rtsj extensions. students should be fluent in the java programming language up to version 1.4 and should be have some familiarity with the nature of real-time programming, though extensive prior experience is not required.



prerequisites


to succeed fully in this course, students should be able to:

design, write, and debug programs using java 1.4
make use of inner classes, including anonymous inner classes
make use of the threading facilities of java 1.4


delegates will learn how to


control garbage collection induced jitter in thread release
create realtimethread objects, and use schedulingparameters and periodicparameters to control thread behavior
control concurrent access to resources and describe priority inversion and the priority inheritance algorithm
understand the constraints that apply when using objects in non-heap memory, and issues that might arise when using library apis in non-heap memory
use asyncevent, oneshottimer, periodictimer, and asynceventhandler objects to provide timed and asynchronous behavior
control the queueing of asynchronous events to limit the impact of out-of-spec events or handlers on other parts of a system
interrupt threads asynchronously and control their behavior under such conditions
use portals to access scoped memory
describe and use appropriately the scoped run loop, encapsulated method, handoff, timed algorithm, multi-scoped object, wedge thread pattern
use overrun handlers to limit the impact of out-of-spec threads on other parts of a system
